I just got a new Tabby kitten thats 6 weeks old, Buddy is my golden retriever who is 7 years old and has been with us for all of his life. As soon as i got home with the new kitten in the kennel, i let my dog in and he started sniffing the kitten while it was in the kennel then after a minute of my dog sniffing the cat hissed and my dog started barking. I know this may have been a dumb thing to do but how do i introduce them to each other so they can start being like friendly with on another?
