Roxy was here for a visit(my grandparents pit/bulldog mix) and she was out playing with my labs. I turn on the hose for my black lab to play in and Roxy comes out of NO WHERE and starts "attacking" the water,lol. I mean full force jumping up and biting at the water. then I was spraying it in-front of her and she was chasing it like a cat,lol. When I turned off the hose she took it in her mouth and ran! She has been around my labs since she was 8 weeks till now, 6 months or 7 cant remember, and my mom said she is learning this from tank. Tank does the EXACT same thing. So does your bullys do it or is she learning from my dogs? She was also TERRIFIED of going into the lake 3 weekends ago then I took my dogs and she went right in after them(it is really shallow and she was on a leash till she learns how to swim). She kept going in and out with or without them after that.
