Your 9 month old dog and your 2 month old dog fight what should you do?

1: Be thankful their only puppies. You tell them no in a low voice so it sounds like a growl, spank them (not to hard! like a cheek pat) or put your hand around their muzzle. In a pack this symbolizes that you are the alpha and NO ONE gets into any fights unless you say so. Then pick them up, put them in different rooms until they calm down and then let them back out. At night put them in two separate kennels somewhat close to each other (in your room so you can hear them) so they get used to each other without their teeth (if you so much as even hear a begining of a growl in the middle of the night you yell at them and use your hand like directed above. Watch them carefully after that, for months even. Any time they bristle, snarl, growl, show teeth or anything else in a threatening way that is not playful then you repeat the process until they understand. If they continue to fight after about 4 months, you need to get rid of one of the dogs.

2: When they are grown, you can not ever let them fight. They will be more dangerous and can start to hurt people and that will get them put down. If they fight each other, well you need to get rid of one of the dogs because that is again dangerous and one of them could end up dead and then your other dog will either be put down or they will only be allowed to leave the yard without straps around the muzzle, neck and head. They won't even be allowed to sniff another dog with out the government knowing about it.

Fun Fact: 21% of dogs and 7% of cats snore.
