We got a Bullmastiff puppy male & a british x Frenchie puppy female within two days of each other at the age of 8 weeks old (both are now just over two years) we found they constantly wanted to rough & tumble....how we got around this was two crate them seperately for calm time & before popping them in their crates we each would give them long slow calming pats before nap time's, also gave them ice cubes to lick when playing which kept each pup busy.
We took them to puppy school sessions seperately & made sure each pup had one on one time with us without the other pup , all in all we had been told that it would be a nightmare raising two pups together but we kept a positive mind & enjoyed their puppyhood, we would do it again in a heartbeat.
We also have a female british Bulldog (both our girls are speyed) & the three dogs all get along apart from the very odd grumble, I think the key is to be the pack leader & have zero tolerence for fighting.
Congratulations & best of luck to you.
Edited to say: Our fur kids are crated when at home by themselves.
