Thanks for the responses people. Do not be misled by this Vitaly character, his knowledge of the breed is obviously flawed, I consider myself somewhat of an expert on the bullmastiff breed and have studied their history, health, and care. I will answer any questions through PM if anyone is interested. As for this individual who is dead set on showing everyone his ignorance, I would hope that some action could be taken in order to keep him from wasting all of our time. I Posted in order to sell my dogs, I happen to love predatory fish, so I figure if anyone is interested in trading for a puppy, it would be a good opportunity to establish a relationship where both parties benefit. All of the people I have bought pygos off of seem to be great people, and most had dogs as well. I have to say I'm disapointed that my first post is attacked by out of spite by someone with no knowledge of the breed in question. These kind of ignorant responses should not be tolerated on the board. This is the kind of person who I would not sell my dogs to at any price. Seems like he has anger issues doesn't it? Anyway thanks again for the respectuful responses and I will keep you updated on the planned breeding. The female is due for her checkup soon.
