Story
Bureau of Dog Law Enforcement—Kennel License #2617Could he do well with kids? Yes, with children around 12 years old, on a kid-by-kid basis.Could he do well with other dogs? Yes, on a dog-by-dog basis.Has this dog lived with cats? Yes. [The Lycoming County SPCA does not “cat test” dogs per the Association of Shelter Veterinarian’s Guidelines for Standards of Care in Animal Shelters.]---What volunteers have to say about this animal:Meet Bear – Gentle Giant, Soft Eyes, Brave-in-ProgressBear is a 1-year-old Spanish Mastiff–American Pit Bull Terrier mix weighing in at a very huggable 89 pounds of sweetness. He’s big. He’s handsome. He’s sometimes a little unsure of the world. And those soft, love-me eyes? They will absolutely undo you.Bear is still building confidence, and you can see it in the thoughtful way he moves through new situations. When meeting new people, he may investigate from behind first, just making sure everything checks out before stepping forward. It’s not fearfulness; it’s caution. And honestly, for a dog his size, that kind of awareness is pretty endearing.What Bear Is Like:- Playful and toy-motivated (toys help him relax and shine!)- Gentle with his size — navigates beautifully on leash without pulling- Allowed handling, though prolonged contact made him a bit tense- Occasionally jumps up when excited during playWhen meeting another dog, Bear came in a little enthusiastic at first, but he respected the other dog’s space and showed appropriate social skills while trying to initiate play. That tells us he’s learning — and learning well. He can feel uneasy with fast, unpredictable movement (like someone running around), but give him a toy and a calm vibe, and you’ll see his playful side come out. Toys are his bridge to confidence.Bear’s Ideal Home Looks Like:- Kids around 12+, on a case-by-case basis- Other dogs, pending thoughtful meet-and-greets- Possibly cats (he has lived with them before)- A patient family who will help him continue building confidence- People who understand that bravery grows with supportBear is what we lovingly call a “gallant softie.” He’s large and strong, but inside he’s sensitive and thoughtful. He doesn’t barrel through life. He tiptoes a bit, looks around, and then, when he feels safe, lets himself play. ---Condensed Staff Assessment Notes: Bear is a playful young do

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
PLEASE NOTE! Unless stated otherwise, our dogs and puppies are located in Arkansas, and transported to the north/northeast once adopted. We do occasionally have dogs/puppies placed in foster homes in the north/northeast. In the cases where the pet is somewhere other than Arkansas, it will be noted beside the name of the pet.Urgent need for foster or adopter!! Johnny (renamed to Ozzy) has become urgent. Not because he is dangerous in any way, but because he's inconvenient. He makes a mess in a crate, and barks when left outside, and now neighbors have called the police because he was barking while his adopter went out to dinner. Clearly, he has some separation anxiety and it breaks my heart that he is going to have to make yet another change. He needs a patient adopter. He was NOT like that while he was in Arkansas. He was very well adjusted. I feel that he is not getting nearly enough exercise. I believe that is a big part of the problem. And I think the other part is that he needs more time to adjust. Johnny did great with other non aggressive dogs at doggy daycare while here in Arkansas. He has not been with other dogs since going to his home in January. Johnny adores all people. He did great with kids here, but was never around any really small kids. We have no reason to believe he would not do well with them, but he might accidentally knock them down, because he himself is just a giant baby and doesn't know his size. Johnny is just over 100 lbs, is about 2 years old, and is located in New York.

This includes microchip, spay/neuter,  up to date on age appropriate vaccinations, dewormings, flea/tick treatment, and heartworm test (if over 6 months old) as well as heartworm treatment if they test positive. There is a transport fee of $150 per dog, depending on the transporter. We use Pack Leaders Rescue Dog Transport most often, but also use Hearts Transport as well on occasion.
