3. Sketch

Young (2 years) · Male · Beagle · 98 mi from Jacksonville

Sketch is really a happy-go-lucky little guy who seems to have a permanent wag in his tail! He loves getting affection from people, enjoys going for walks, and has a lot of fun with toys-- especially the ones with squeakers which he renders squeakerless! Sketch likes other dogs and is playful without being overpowering, and he has done well in a home with cats. House training is coming along great and he learned to use the doggie door very quickly. Things Sketch is still working on are to keep all four paws on the floor when greeting people and he is also still figuring out some household boundaries.

Read more about Sketch

Although he accepts verbal corrections well, his curiosity sometimes just gets the best of him. He’s been known to climb on top of his crate in pursuit of cat food, hop onto the metal storage can on the patio to peek through the kitchen window, and use a side table to keep an eye on the yard guy at work. Clearly, he doesn’t want to miss a thing. He is not frequently vocal, but the few times Sketch has been heard to sing out the famous beagle arroo it is definitely rousing! At night, he’s fantastic in his crate. He may whine a little when the sun starts coming up, but he doesn’t make a big fuss. Sketch is easygoing about handling. He let his foster mom clean his ears and handle his feet without complaint. All in all, he’s a loving, cheerful guy with a curious mind, a playful spirit, and plenty of personality. Sketch is also heartworm negative and ready to go on sleepover.

4. Scribble

Young (2 years) · Male · Beagle · 98 mi from Jacksonville

Scribble was a little timid when he first arrived but the other dogs in his foster home are really helping him to gain confidence. He follows them in and out of the house and they all enjoy hunting for lizards. He is usually pretty quiet but when he gets on a scent he lets out that delightful and musical beagle ARROO! Scribble is doing really well with house training but is still a youngster and with his chewing urge seems to have a liking for flip flops. Foster mom redirects him to appropriate chew toys which he also likes - and plush toys. He is most definitely a happy boy with a wagging tail and although he requests back scratches and petting, Scribble is still a little uncertain with people and will sometimes cower down.

Read more about Scribble

He does not seem to be familiar with dog beds and chooses instead to curl up on a throw rug. The other dogs in the house often inhabit the couch, but he only jumps up when they are announcing something worth watching for out the nearby window. There are several cats in his foster home which he completely ignores. He does not ignore food though - oh no, he is typical beagle there and good thing foster mom is experienced as he has found the kitchen counters and garbage can to be a temptation. We would prefer for Scribble to have a fenced yard and he would do best with another dog. This little 2 year old is learning well and will grow up loved. Scribble is neutered, vaccinated and tested heartworm negative so he is ready to go on a sleepover!

5. Odette

Adult (5 years 11 months) · Female · Boxer / Mixed (short coat) · 47 mi from Jacksonville

Odette has been at the shelter since July and is as sweet as they come. When the shelter noticed a mass on her vulva that was growing in size they sent out a rescue plea for her and we said yes please!

We cannot wait to address the obvious chronic allergies and infections her thickened ears and swollen paws have had to endure and get her mass addressed.

6. Pigeon

Adult (2 years 11 months) · Male · Chihuahua (short coat) · 47 mi from Jacksonville

Pigeon’s sad little face had us fake (and maybe a little real) crying immediately. He was found as a stray covered in fleas and underweight. We aren’t sure what this little dude’s past was like before, but we know it will be pampered and full of cute outfits from here on out.

Pancake is just a goof who has been sitting at the shelter for a couple months already. She is deaf, and we are very excited to get to work with @savvydt to help our girl blossom.

8. Porkchop

Young (1 year) · Male · Black Mouth Cur / Mixed (short coat) · 47 mi from Jacksonville

Porkchop is just a good guy whose luck had ran out. (Until he met us that is.

) Him and others were set to be euthanized in order to clear kennel space at a small crowded shelter and we scrambled to be able to pull him just 24 hours before his set euthanasia date. Porkchop will be overlooked no more!

9. Laredo

Adult · Male · Terrier / Mixed · 31 mi from Jacksonville

Meet Laredo! Laredo spent the first 5 ½ years of his life with the only family he had ever known, from the time he was just a few weeks old. When circumstances changed, Laredo suddenly found himself without the home and family he had known his entire life. Now, this handsome boy is looking for the second chance, and forever home, he deserves.Despite everything he has been through, Laredo is a sweet, smart, people loving boy who enjoys meeting new people and being part of the action. He already knows sit and paw, comes when called, walks very nicely on a leash, and is both house trained and crate trained.

Read more about Laredo

He’s also quite vocal and loves a good howl when he has something to say!Laredo is currently spending time with a professional trainer, where he is doing very well and giving us the opportunity to learn even more about him. He has done well with large female dogs and may also be compatible with more submissive large male dogs. He can be selective with confident male dogs, so any potential canine sibling would need to be carefully considered and appropriately introduced. His compatibility with smaller dogs is still being evaluated.One important thing we’ve learned about Laredo is that he really needs companionship. He does not do particularly well being completely alone and is happiest when he can be with his person. If his people are going to be away, Laredo needs the companionship of other compatible dogs around him. He would do best in a home where he won’t routinely be left completely by himself for long periods of time.Laredo does have a strong prey drive and cannot live with cats, chickens, or other small animals. We are also looking for a home without young children.Laredo loves being outside and having room to roam and explore. He does have a history of escaping, so secure fencing is important, and he should not be left outside unattended. Since settling into his current environment with plenty of space and secure 6-foot no-climb fencing, he has not been showing signs of trying to escape. Keeping him exercised, engaged, and included will be important in his new home.Laredo needs an experienced, committed adopter who can provide him with structure, consistency, exercise, attention, and plenty of love. He is an intelligent dog with so much potential, and with the right person willing to understand his needs, we believe he will flourish.After spending 5 ½ years with one family, we want to make sure Laredo never has to start over again. We aren’t looking for just any home for him, we’re looking for the home that will finally be his forever!

12. Fallon

Young (6 months) · Female · Hound / Mixed (short coat) · 35 mi from Jacksonville

Meet Fallon — a little lovebug learning that the world can be a safe place.
Fallon is a 5–6 month old sweetheart who is looking for a very special forever family. She’s silly, loving, playful, and absolutely melts into you once she knows she’s safe.
This girl is timid and easily overwhelmed, especially by new people, loud noises, and busy environments. She may bark or growl when she’s scared, and when things feel like too much, she’ll retreat to her safe spot. Fallon isn’t being difficult—she’s learning to trust after someone was unkind to her. She needs a patient person who will give her time, space, reassurance, and lots of positive experiences.
Once Fallon feels comfortable, you’ll see the real her: zoomies, toys, cuddles, hugs, kisses, and the sweetest little smile.

Read more about Fallon

She loves playing with toys, enjoys snuggling in your lap, and just wants to love her people and be loved right back.
Fallon’s ideal home: • A quiet, calm household and surroundings • Someone patient who understands that confidence takes time • A securely fenced yard rather than busy walks for now • A family willing to help her build trust at her own pace • A home where she can decompress and feel safe
She’s crate trained, mostly housebroken with occasional accidents, and does wonderfully with other dogs and cats. She’s also good with redirection and listens well. Because she can be easily frightened, a chaotic or very busy home probably isn’t her best fit.
Fallon may not be the dog who wants to accompany you everywhere—but she could be the dog who becomes your best friend at home. Give her a little patience, and she’ll give you her whole heart.
Fallon is waiting for someone who will see the scared little girl underneath and help her discover the confident, happy dog she’s meant to be.
Could you be her safe place? ❤️

13. Cardi

Adult (6 years 3 months) · Female · Beagle · 98 mi from Jacksonville

Cardi's purpose in life seems to be loving and being loved by her people. She enjoys meeting new people and is thrilled at the slightest attention shown to her. Being next to you getting pets and scritches is her absolute delight. Cardi plays with the other dogs in her foster home, but she has her limits with them and would also do just fine as an only dog. She does not like to be messed with when she is lying down and she will definitely tell them to go away if they get in her face while she is relaxing. We do not know about Cardi with cats but she does not seem interested in any prey. Her house training has improved immensely in the few weeks she has been in her foster home (arrived 8/21), and she has been crated for up to 6 hours with no accidents.

Read more about Cardi

Unsurprisingly, Cardi is very food motivated and will try to steal others food. She loves her treats, especially the soft little meaty ones. Currently Cardi is not leash walked and she loves to run in her fenced yard. Her energy level is perhaps slightly above moderate. She is heartworm positive but we expect her treatment, which is scheduled for October 1st, to go well and she should be ready for sleepover around October 5th.

Marble has a spectacular personality, is super smart and eager to please. She is a high energy pup who is always ready for fun. She loves to play with other dogs, go swimming in the pond or river, take a stroll in the woods or beach....whatever you do for fun, she's ready to go along! She is a sweet cuddle bug when it's time to relax. She's a Rockstar in her training sessions, quickly learning new tricks and skills. You can't go wrong if you're looking for a fun pup with a big heart.

15. Finn IV

Young (1 year 8 months) · Male · Beagle / Hound / Mixed · 98 mi from Jacksonville

Finn is a really happy, playful guy! He definitely needs another playful dog and he's having a blast with the other young boy in his foster home. They have a great time sharing toys and romping about. Please see videos below. Finn loves going to the dog park and showing off his running speed, and h⁰e also loves the water. One day the pool was not available so our silly boy climbed into a water bucket. Finn does still have a few puppy traits. He will go after shoes... even when you are wearing them... he puts his feet on the counter to investigate... and he likes rugs and blankets. But foster mom is a good trainer and Finn is starting to understand "no" when he gets into those things.

Read more about Finn IV

When Finn is left at home alone he is in his crate. He does cry for a bit but settles down pretty quick and he doesn't destroy anything in the crate. He sleeps quietly in his crate at bedtime. Finn definitely has a high prey drive and will chase squirrels and is definitely not good with cats. His foster mom is teaching him he can't chase squirrels on the leash, but it's a work in progress. He's not a big eater and not very food motivated (toys work better). At this point in his very young life he seems to relate more with other dogs than with people, but that could change over time. He mostly asks for affection when he sees his foster brother, Jasper is getting lots of attention. We think Finn may possibly be really good at agility. His prey drive might transfer well to stuffed toys but currently he is deprived of those as they are just not allowed in the home because of the other dog absolutely destroying them. Finn is heartworm positive but will be treated at the end of August and he will be ready for sleep over the first week of September.

16. Robin Egg

Adult (5 years 1 month) · Female · Terrier / Mixed (short coat) · 47 mi from Jacksonville

We make a promise to our Swampies that once they are with us they will always be safe and loved. But sometimes, no matter how hard we try to prevent it, a promise gets broken. Three whole years of Robin being in her “forever” home and now she is back in our rescue yet again.

Read more about Robin Egg

We are heartbroken for Robin, who is confused and stressed in boarding - the only option we had with 30 minutes to make a plan for Robin’s future. Truthfully, Robin was not an easy dog for us the first time we had her. She was always sweet but she had no interest in humans other than to use them as a springboard and she had lots of, “little kid at a birthday party who had too much cake and missed nap time” type of energy. Robin could have ended up a million other places, many of which we believe would have led to her being pent up, overlooked, and declining in a shelter system she couldn’t get out of. We believe Robin found us for a reason. We worked to help her excited anxiety, we treated her for heart worms, and even sent her off to a training program which did wonders for her. And still we had Robin for a year before she got adopted.

Now, three years later it’s obvious how good home life has been for Robin. She is more settled. She wants affection and sits with her butt right next to you and leans in for pets. She is a different Robin we are getting to know again, but still Rob. She still has her very own unique, happy zest for life, and she still has the cutest stinkin’ happy face. Robin is cat friendly, older kid friendly, no dogs but is not reactive and is dog safe, and she is nondestructive in a home. She also has free life time refresher courses with her trainer. Robin is looking for someone who loves her for her quirks, not despite them. Please help us share Rob. She needs a foster or adopter ASAP. We are very worried she will regress from how far she has come if we cannot get her out of boarding. She is confused and struggling to understand where her family went and we swore to her we would do everything to not let it take another year this time to find her people.

Once a Swampie always a Swampie, and this time forever WILL mean forever.

Adult (4 years 6 months) · Female · Beagle · 98 mi from Jacksonville

Colleen is a tender soul and a real people lover. She is also very good with other dogs, both male and female, and gentle with cats. One cat she met bopped her on the nose and Colleen just rolled over on her back. :) She was seen being dumped from a car, but fortunately she was rescued and taken to a very good shelter. She has now settled in well in her Florida foster home. She has a moderate to low energy level, will occasionally play with toys and sometimes with other dogs. Although she likes her food, she is not super food motivated and a little crazy like some beagles can be. She also walks well on leash.

Colleen will make someone the most calm, serene and loving companion. She tested positive for heartworms but has completed her treatment and ready for a sleepover. She does need a home where people will not have to leave her alone very much because she has exhibited some separation anxiety.

Why adopt an adult dog in Jacksonville

An adult dog's personality is fully formed, so the rescue can tell you how they are with people, other pets and busy households. Many have lived in foster homes and are already house-trained.

Grown dogs need less supervision than puppies and often know the basics, like sitting and walking on a leash, which suits people who work or have young children.
