Hi, I like dogs
I do too! The dog is the first animal ever domesticated.
which kind of dog you had ?
I have a mixed breed but he's trained well. Dog training began around Roman times.
Yes, they learned from ancient Egypt. How interesting it is , knowladge is travelling around the world even they didn`t have internet
Yes, dog training occurs from interactions with different environments so the environments are probably similar.
they used them in wars.they used Mastiff-type dogs 
That makes sense considering English Mastiffs are extremely large.
