Aggressive Puppy

My family and I just adopted a Golden Retriever puppy who is very aggressive with strangers and dogs?
We have a pug plus 1 year he loves all that, however our golden puppy is 7 months and recently bought a muzzle for him at the dog park, which have been put in a small cage, scenario because it becomes totally aggressive growling total package that is very scary I need serious advice please Thanks Thank you all for the answers that I have two daughters 10 and 12, which she loves. My twelve proposals I love to write him this.We
My dog does that too. I managed to train my baby rot Shep / Tolerate other dogs. She loves his package now, but still uneasy around other dogs. He grew up in a wolf to the vet one day. I used a box with a separation thin rod and put it in the center of the room. I weighted down with a weight on top, enclosing a bark collar no, and closed tight. Published my first ever smaller dog barking, put on a little jolt. After fifteen minutes, I put my dog and let the sound box and neck removed for the rest of the day. The next day I did it again. I did it for about a week before I could release my other dog. It took about a month to do this until you trust it in the yard with my dogs while wearing a muzzle. I did it for half an hour every day until she was traveling with them. As for foreigners, I can always do the house of a man. Women, who warmed up, but men tend to bite. I did not understand that one out yet. : / If it is a bit too much for you, call me your veterinarian or a behaviorist.
