Story
Move over, Godzilla… there`s a new lovable giant in town! Meet King Kong, a goofy, dorky Mastiff mix puppy who is still trying to figure out what to do with all those legs, paws, and that BIG personality! He`s basically a walking, wiggling, wrestling machine with a heart of gold and absolutely no concept of personal space. We think King Kong would LOVE a canine buddy who enjoys playing, romping, and wrestling. He has enjoyed playing with other dogs at the shelter. Another fun-loving dog could be just his kind of partner in crime!Fair warning: this big boy is still working on his manners. He jumps up with enthusiasm and can knock people around without meaning to, so he`ll need an adopter who is physically able to safely handle and walk a strong, growing pup. If there are to be kids in the home should be teenagers.Looking for a whole lot of puppy silliness wrapped in one giant package? King Kong is ready to bring the laughs, the love, and possibly a few bruises to your lifeIf you are interested in adopting King Kong please come to the shelter on Mondays, Wednesdays and Thursdays during our walk-in adoption hours of 12-4pm

Story
Silvio is the best boy. He is so loving, loves cuddles... and any kind of attention. He thinks hes small - still has puppy energy. He turned 3 in January 2026. I have no complaints with him whatsoever... rehoming him breaks our hearts, but he deserves better than the circumstances were facing. He needs room to stretch his legs and exercise on a regular basis. He loves playing in snow, he is so funny when he gets the zoomies lol. He is just the best!! He does so well at dogs parks, we take him almost every day. Gentle giant but protective over his family. He's not the biggest fan of strangers getting too close to us or our home but once they let him sniff & say hi its fine. I would love to be able to visit him occasionally. But he does need more than I can provide at this point so this must be done. You will love every second with him. He keeps life interesting thats for sure. He needs someone with time & energy.
