Rehome Lab mix (Middeltown)

Hello everyone i need to rehome a 1yr male lab mix he is fixed and up to date on shots. Unfortunately we just brought a new pup into the home as a playmate for our teacup chihuahua and he shows aggression towards the little pups when they play. He is crate trained he goes to the bathroom outside and loves to play fetch he is not an aggressive pup towards adults or children or other big dogs he is very playful he just don't know his weight or strengths. I posted a six month old photo of him for an idea what he looks like but if you would like an updated pic message me. Also There is a rehome fee $250 please text show contact info thanks
