Bio: Trouble might be his middle name, but his first name should be Shy-Pup. Trouble is uncertain around new people and will avoid them. The way to his heart is through tennis balls. He’s never met one he didn’t want to chase. Once he gets into that play mode, he becomes a big puppy. Trouble also likes to walk on leash, though his previous owners reported that he can be dog reactive on leash, but dog-friendly off leash. In the shelter so far, we have mostly seen a bit of whining and pulling. He is definitely very strong and needs to learn not to pull quite so much. He is a good option for a family that likes exercise and the outdoors. He appears to be housetrained.
