In the shelter’s words

THE MASTADORS: When our rescue partner Washington Health Outreach sent a desperate please from a Washington property with 90+ dogs and several recent litters of Lab Mastiff mixes (aka Mastadors) we had to help. We have taken in 11 and counting. Animal Information: Meet Arvis, an estimated 3 month old female Labrador Mastiff mix with a gorgeous sleek coat and soulful eyes. She is around 30 lbs and growing. She has no aggressive tendencies toward humans and has lived with a large number of other dogs. We will share more info after she decompresses and we get to know her in foster care. Foster Profile: Arvis was a little fearful at first but is showing she is resilient and wiling to learn. She loves calm respectful kids and her playful side is coming out. Arvis is as sweet and gentle as they come! She loves her toys.. some would say she is a bit of a toy hoarder but in the cutest way possible! She has a very gentle mouth and loves some good belly rubs! When she first came to us she was scared, and could use some help building her confidence. When she met our resident dog, she lit up as she was so excited to see another dog! She gives the sweetest kisses and snuggles and is close to playing with him, so we see that developing while she builds confidence. She is crate trained and sleeps thru the night without a peep! House training is going well. She lets you know she needs to go out by sitting by the back door and does her business quickly once let outside. She is going to be the best family dog! Adopter Profile: Large breed experience required Singler Family Residence required Adoption Info: Adoption fee is $575 which includes spay/neuter, core vaccinations Rabies and DPPV per AVMA standards, any indicated preventative care, microchip with lifetime registration, and recent health check with a veterinarian.
