Meet Finrir (Finn)! Finrir, affectionately known as Finn, is ready to charm his way into your heart and home! About Finn: Finn is an 85 lb Mastiff mix with a heart as big as his size. He's a gentle giant who thrives on one-on-one attention and would love to be the center of your universe! Despite his size, Finn is a total softie. He's non-destructive and a pro at taking his medicine with ease. While Finn prefers to be the only fur baby in the house due to some dog reactivity, he'll fill your home with enough love to make up for it! What Finn Needs: A loving family who understands his need to be the only pet. Plenty of space for him to stretch out and relax. Someone who enjoys leisurely strolls because Finn walks like a true gentleman on the leash! Interested in Adopting?
