Hi guest. As someone who owns a 2yr old Munster called Chance I thought I'd better answer ;)
Personally I wouldn't recommend it for another year. He hasn't gone through the 'Kevin the teenager' stage yet. You would be pulling your hair out if you had a puppy too

If I was breeding a litter soon I would not sell any pups to someone who had what is basically still a baby. Munsters mature a lot slower than some other breeds, mentally as well as physically. I wouldn't be without any of mine, though, they're lovely :D
Why don't you join? There are several Munster owners on here. It doesn't cost anything
