Should we get a bullmastiff???? My hubby & I had a beloved Boxer for 10 1/2 years. We lost him to cancer 3 1/2 years ago.....found out 4 days later I was pregnant. Our son just turned 3 & we desperately want another 4 legged baby. Our boxer was about 100 lbs and the exception to the rules for boxers. He was laid back & very protective! Seems more like a Bullmastiff personality from what I've read. I just have some concerns as all I know about Bullmastiff's is what I've read. I'd LOVE to hear from actual owners. 1. I'm worried about him being TOO protective...like when my son is a little older & his friends come over to play. Will he be gentle with other children if properly introduced? Will he be ok with our neighbors & their friendly little male dog? We of course plan to well socialize him. 2. Is there life expectancy truly around 10 years? 3. The only training we've done is with a stubborn boxer. Are Bullmastiff's hard to train? 4. What questions to ask the breeder? 5. Our son is used to his grandmother's boxer....will it be too hard b/c of the size of the Bullmastiff with a toddler? 6. Any other advise would be GREATLY APPRECIATED!!!!
