Story
Harlow Rin. She is 2 years and 3 months old. Her birthday is May 17, 2024. She is a sweet baby. She does get REALLY excited. She used to get so excited that she would pee. She doesn’t do that much anymore. She does have some allergies. She allergic to wheat, corn, soy, and grass. I don’t know what type of grass she is allergic to tho. She talks back. She will caught an attitude with you. She has a lot of energy and so is very smart. She knows when people are being mean to her. When she meets new people she can be scary because she will bark and growl. Once she calms down, sees you mean no harm, and gets her sniffs in, she’s all over you. She’s overall a great dog. I want her to go to a home with a big yard so she can run to her heart’s content. I want her to be loved. A LOT! She is my first dog and I’m devastated that I have to part with her.I would be happy to answer more questions her.

Dior was born in Las Vegas on Sep 27th, 2020. He loves attention and is a highly energetic dog. Some would say he still has puppy energy. He is house trained and gets along great with kids. We desire for him to go to a home where he can get all of his energy out and gets lots of love from people. He would bring so much light and energy into your life.

Story
What are you waiting for? Apply today! Click here to apply for the pet Macho Man is a 2-year-old pit bull mix who is full of energy and love. He enjoys playing tug, going for a long sniffy walk and cuddling on the couch with a bone. Macho was rescued as a stray, so we don't know much about his history. Here's what we do know: he is a little afraid during thunderstorms, but he just needs to cuddle up on the couch and have something good to chew on. He seems uncertain about other dogs; he's not overtly aggressive or scared, just showing us mixed signals. We are continuing to socialize with control until we find the personality type that opens him up more. We think he could have a house mate if they had the right personality for him. Macho has begun obedience training and knows sit, down, climb, come and we're currently working on heel. He does require exercise during the day but knows how to chill out in the evening and relax. Macho would be a great fit for a semi active household. He has not been cat tested. Older children who are appropriate with dogs would be best for him.

Story
Ruby is a very, very, sweet active girl. She loves snuggles! She's a good eater picky at all. She is part Border Collie and is super smart and again active. She needs a family that is active and will get her out to run and play. She really is a huge lover and gives lots and lots of kisses. She's a bit timid at first but warms up quickly. No problem with other dogs at all.
