Story

We got Dutch from a foster home a few years ago and our family has grown, and moved, and grown, and moved. We love Dutch but he’s not getting the care and attention he deserves, we leave all day for work and then immediately have sports in the evenings which means Dutch is outside alone all day by himself. he’s very social and sweet and loves walks. His hips have been achy lately but he still loves to play and walk. He’s a big guy but doesn’t jump up or act overly rambunctious! Great teeth and coat! He hardly barks, unless someone unfamiliar is approaching the house so he’s great as a guard dog, but he might just lick them to death if they get too close! He’s very friendly with people and knows how to be gentle with food and toys. He does like to power chew so he needs heavy duty toys!

Hello, my name is Zeus! Isn't that an amazing name? I was a stray, but now I'm here at the SPCA, hoping to find some kind and loving people to adopt me and make me part of their family! I'm very obedient and intelligent. You might feel a little intimidated by my size, but I'm a big boy with a sweet, loving heart! I absolutely love playing with squeaky toys—they're so much fun! Fun fact: I can catch a squeaky toy in mid-air! Together, we can make unforgettable memories. Let's make this pawsome! ##2284747##
