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

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
We adopted Hershey shoo we call moose often from a kill shelter 4 years ago when we lived in a home with a large fenced in yard and we never had an issue with her. We needed to move no fault of our own ( the picture with all the boxes was in the packing process) and we unfortunately had a hard time finding any rental that would allow dogs, unfortunately the house we found didn’t have a yard. We didn’t think that would be an issue till it was, she does not like rocks or stones or the broken sidewalks, she has resorted to refusing to go outside often far to often. Due to major surgeries in my end and work schedules of the rest of the home we feel she would be much better in a home with a yard and someone who can spend much more time with her. We are sad to let her go but we do feel it’s best. She will not bother things that aren’t hers if you tell her no. She loves toys she can tear apart, she is UTD on her rabies shot. She really is a good dog that needs more love.
