yes. All my dogs have it. Not bad thoughh. What you should try to do is 1) keep them in seperat rooms while they eat or 2) just keep them further apart. With our dogs we HAVE to keep them at least 2 ft apart. One time Tyler attacked Fanny because she walked up behind him and just barly touched his tail. She had to get 15 stiches. PLZ DON'T WORRY! That wasn't to scare you. If you just work with him and it should get better. For Tyler it was too late. He had it the day we got him. Good Luck!
