Story
I'm Diego, a striking 2-year-old chocolate and blond brindle Mastiff mix, and I've got the heart of an adventurer! 🐕 At 63 pounds of pure energy and loyalty, I'm already neutered and crate trained—ready to be your partner in crime. I thrive with active owners who can match my enthusiasm, and I'm fantastic with other dogs, so playdates are always a go! If you're looking for a friendly, energetic companion who'll stick by your side through thick and thin, come meet me today. 💪❤️ Local adoption fee is $300 (in TX) Out of state adoption fee is $550 (includes transport to your area)

Story
This guy has a story let me tell ya. His name is pronounced Mah-zi and means "lucky". Well he's sure lucky that somebody had the good sense to dump him in our town so that we could become his new tribe. Mazi was lovingly owned and lives in Chicopee Mass but his owner had to move and couldn't secure housing for them. He rehomed him to an older gentleman in Springfield Mass. In the span of six months, Mazi found himself dumped in CT. We did recon with his microchip and got the scoop. So now he's looking for his forever home, and preferably no dumping this poor dog. He's already been thru enough. Mazi is good with docile female dogs his size. He's a little mouthy so only older kids until he settles in and gets his bearings. We are under the impression that his mouthiness is from stress in the kennel. He loves car rides and walks. You could take him everywhere but he's strong on a leash. We will help to teach you how to walk him and use training techniques. He's not cat tested but we'd say, um no. He's getting fully vetted on 9/15/26. He can go home two days later.

Story
Tanner is a handsome boy! He loves to take walks and lean into you for pets. He is a great car rider and really doesn't care where you are headed - he just wants to go along. He gets along with other dogs, but doesn't actually need a canine companion. He is not all that playful. He would love to be doted on and receive all of your attention. He is a pretty low maintenance dog with a good attitude.The Adoption Fee Includes Age-Appropriate Vaccinations (DA2PPV, Bordetella, Rabies), Deworming, Spay/Neuter, Microchip, Flea, Tick and Heartworm Treatment and Prevention, and Sheltering. Adult Dogs are Heartworm Tested and Treated as Needed. Tanner's adoption fee (if picked up locally in Crossville, Tennessee) is $225. If transport is needed, his adoption fee is $525 (out of state, East Coast, Great Lakes or New England regions).Thank You for Your Interest in Adopting a Canine Companion from Foccas-tn.org!To Apply Please Copy and Paste to Your Browser:https://service.sheltermanager.com/asmservice?account=hb2428&method=online_form_html&formid=41

Story
Rufio is a gentle soul. He is a little shy and more on the quiet side. He does good with other dogs, even small ones.I just can’t say enough sweet things about this pup. He is good in a car and is learning the leash. It takes a little while for him to trust new people, but once he does, his goofy and sweet personality shines!Rufio is medium energy and would do great with any family with a little patience. Rufio is not completely potty trained. He still marks in the house but is working on that.Located in Houston, Tx. Transport to most states available for an additional fee of $300.

Story
Welcome Pocket to CCPAL Rescue. Pocket is a 4.5 month old Mastiff/Great Pyrenees. Pocket is extremely affectionate and stunningly beautiful. This whole litter is soft, cuddly and affectionate. Pocket would be great with a family with children. This dog has guardian breed, and would be a great family dog. She would be wonderful for a family with a dad that travels and wants to see his family has a dog that will watch out for them. Yeti went to a family with younger children and he is doing great. This is Pocket’s brother. We prefer children to be 8 or older. She should be 60 pounds full grown. She likes water, decent on a leash and area trained. She will go on a potty pad. She is good with other dogs bigger than herself. Her dad is a Dogo and mom is a Great Pyrenees. She is energetic but can calm down and be extremely cuddly and affectionate. She has a soft coat and not a huge shedding dog. She has shorter hair a little more like the DOGO dad. This breed is a guardian breed family even though she shows no signs of guarding anything at the moment. She is getting his vaccinations and will be ready for her forever home soon. She is currently in Texas and can be adopted locally or we can work with one of the wonderful transporters to get her to Washington, Portland, Minnesota, Vermont and all along the East Coast. Her adoption fee is $600 and transport is $200. This is a very desirable breed. Please be patient when you put in your application. We are being very careful in vetting people and we are a small group of volunteers. Rhode Island and Massachusetts are not states we adopt to because of the regulations imposed by these states Contact Marlene at 210-867-1769 or email to ccpalinquiries@gmail.com if you have questions.
