What's this boxer good for?

you might be able to make a catchdog out of him. the aussies seem to like them for making crossbred hog dogs. either way they have weak mouths & after 3-4 yrs will be gumming their food.
before you get into anything that may involve a lot of running look at his structure to make sure he is upto the task. if he is very undershot like a giant pug (show lines) then excessive heat & running can be deadly. OTH if he has the old working muzzle then he should be able to go for hours. also the breed has some issues w/ hip dysplasia & ACL which can be aggravated by too much excercise. so you will have to keep a close eye as you work him & be ready to provide first aid for overheating & exhaustion.
