Omega-3 Improves Your Pet Health

I have a 9 yr old Lhasa Apso, a 2 yr old Siamese, and a 1 yr old DSH. When I got my first cat, she seemed okay with him, but when I brought my other cat home he was a TINY thing and she kept wanting to play with him, and knocked him over so he hissed at her. She is older now, and had some health problems, but whenever the cats get close, they wont be doing ANYTHING, and this isnt ALL the time.. but they walk by her and she starts barking, chases them a few steps, and lies back down. I have started to go over and tap her nose and say no, and the other day she went over to one of the cats wagging her tail and trying to play with him and I gave her LOTS of praise. Am I doing the right thing? Should I be doing more?
Thanks

Her name is Daisy, we’ve had her since she was old enhough to be weened. She’s very loyal and very obediant, but when epopel come into the house she barks like mad. It’s not really a problem exept it’s very annoying. She’s two years old, perfect health, and no past tramas. Please don’t suggest a dog trainer, I need somthing I can do at home. We’ve tried punishment, distraction, and suclusion None of which work. I can deal with /alot/ of dog problems, but I can’t seem to break her of this barking habit. Please only serious answers, and I don’t believe in cruelty. Also, muzzles don’t work so thats out of the question.

He is a two year old housebroken dog with no health problems. I don’t know how to make the barking and peeing stop. My other dog has no problems being in her kennel.
