Story

Nala is a beautiful brown and gold brindle Mastiff who was born July 9, 2024. This big girl weighs about 85 pounds and has a short, smooth coat. She is spayed, fully vetted, microchipped, current on vaccinations, and current on heartworm and flea and tick prevention.Nala came to Hillcrest Animal Rescue after being dumped by a breeder. She arrived emaciated, heartworm positive, and despondent. This sweet girl seemed to have almost given up. With good food, medical care, and plenty of love, Nala has made an incredible transformation. She is now at a healthy weight, has completed her heartworm treatment, and has become a happy, outgoing girl who is ready for her forever home.Nala lives with many other dogs and does well with them. She has made several canine friends, although she does not appreciate another dog trying to steal her food. She is not good with cats.As much as Nala enjoys her dog friends, she is really a people person. She loves attention and gets along wonderfully with adults, children, and seniors. She is affectionate, engaged, and ready to devote herself to her new family. Like a typical Mastiff, Nala also believes that 85 pounds is the perfect size for a cuddle bug.Nala is house trained and crate trained, walks well on a leash, and has great house manners. She is comfortable being left home alone and is also a good traveler, making her a wonderful companion for someone who wants a dog to join them on adventures.Nala has come a long way from the frightened and neglected girl who first arrived at Hillcrest. Now she just needs the final piece of her story, a family of her own.

Good with kids, Good with dogs, House-trained, Spayed or Neutered,

Story

Wolfie was initially saved from the euthanasia list at a high-kill shelter because the staff thought he was so awesome, and was pulled by our rescue when he was placed on it again. He is a loving, outgoing boy just waiting to totally devote himself to his humans. He gets along great with other dogs as long as they are not mean to him. He plays well with all the puppers in his foster home, no matter how old, young, big, or small. He loves humans of all sizes and ages and enjoys all the attention he can get. He is calm going for rides and great on a leash, so he would be a terrific go-everywhere boy. He is crate- and house-trained. He is crated in his foster home only because there are quite a few dogs, but he would be fine without a crate.Wolfie is fully vetted - neutered, current with all vaccines, microchipped, on flea/tick prevention, and has had heartworm treatment since he was positive.

Story

Meet Bakugo This handsome, sweet-natured pup is full of charm and personality. Because of his size, he’d do best in a home without young children, small dogs, or cats. Bakugo is a sensitive soul who loves being close to his person and isn’t a fan of spending time in a crate—he’d much rather be your constant companion. He’s house-trained, vaccinated, and neutered, and is ready to bring love and loyalty to his forever home.
