An open book.Bubbles is the kind of dog who walks into a room and immediately becomes everyone`s best friend. Outgoing, social, and endlessly affectionate, he`s skipped right past the `awkward shelter phase` and gone straight to ready for my close-up.Dog friends? He`s open to it. Couch space? He`ll need half (at minimum). A family to call his own? That`s where YOU come in.Bubbles flew in a stray and is ready to fly out as family. All he needs is a front door to call his own — and maybe a really big dog bed.

Story

I am 53 lbs, and I am looking for my forever home. Adoption Donation: $450 Shy is a beautiful girl with a stunning brindle coat and a gentle, sensitive soul. True to her name, she can be a little shy at first and may need a minute to warm up to new people. But once she feels safe, her sweet personality shines through. Shy loves affection and will happily lean into you for pets once she trusts you. She has such a tender heart and just wants to be close to someone who cares about her. She came to us when her owner sadly became homeless, and the change has been scary for her. Shy is simply looking for a safe, loving home again — a place where she can relax, feel secure, and be someone’s beloved companion. With a little patience and kindness, Shy will reward you with quiet loyalty and lots of love. All dogs are microchipped, neutered, current on all vaccines, heartworm tested (if age appropriate), and up-to-date on preventatives at the time of adoption. All household members and any dogs from the household need to be present to be able to adopt. A photo ID will be required at the time of adoption. Appointments are recommended. All applications are considered general. Specific animals are NOT put on hold for adoption. When you visit, our adoption counselors will be able to make suggestions based on the type of pet you are looking for and help you find the best fit for your family. Animal House Shelter cannot guarantee the breeds of the adoptable animals. The animals are posted on the website as the breed or breed mix based on their physical characteristics they most resemble. We also cannot guarantee the ages of our adoptable animals or how large puppies will be when fully grown. We look forward to seeing you soon!
