I bought a puggle at 2 weeks old in the streets. I love Tim bottle fed him and he’s now 11 month old vicious aggressive and hates people. I also have to Toys portals which he is too rough with. this is the first dog I’ve ever owned that has been this aggressive and he’s also need it my children and has Nick me in my face And drew blood when I was playing with him. so I don’t believe it’s how you raise certain dogs I think insert in dogs it’s in there blood. so I had no choice but to sadly post em on the Craigslist.
