Boxers

Feeding
Boxers should be fed 3 times per day, 1 and 1/4 cups, as for the brand of dog food I'd recommend whatever you want, as long as your boxer dog eats it. Go to the pet store and browse dog food, and see what you think your dog would like. Don't fall for those "meat by product" commercials. If they are terrible for dogs, it would be illegal to sell them.

Playing
Boxers are puppies at heart for their entire lives. Even when you're exhausted, they'll still be wanting to play. Be prepared to get up early because they want to get outside and do their business.

Pairing
If you are introducing a new boxer to an older boxer, do so outside. The older one can lead the puppy inside, and will take great pride in teaching the puppy everything there is to know about being a dog.

Behavior
Boxers are very loyal to their families. My boxer sometimes gets slightly jealous when I pet the neighbors dog and will come up to me and show me affection until I pet him too. They typically do well with other dogs, the only thing to watch out for is the boxer playing too rough with a puppy or new dog.

Training
Boxers can be clicker and treat trained. My personal favorite is the treat training, because it doesn't take as long and is equally effective. To train your dog, for example "sit" tell him the command, "[dog name], sit!" and push his butt down until he sits, then give him the treat, and praise him. Keep doing this until he does it on his own. Make sure you give the treat within seconds of him completing the trick, or he may not see the treat as a reward for his trick. He may just see it as him getting a treat for no reason.

Shedding
Boxers have hair and do occasionally shed, but not a lot compared to other breeds like golden retrievers. You may notice a couple of hairs here and there on your clothes. Boxers are not hypoallergenic.
