We have just welcomed a 12 week old Beagle puppy into our family, which consists of an 8yo male (not entire) JRT who has been an only dog most of the time, 2 cats, horses, sheep and chooks. Admitedly we have only has "Lilly" for 24 hours but "Jimmy" the JRT is having a little trouble adapting, growls at Lilly when she goes near him or me or my husband and has generally not wanted to have anything to do with her. He is quite a dominant dog and can be quite fussy about what other dogs he likes.
I'm just after some thoughts/idea's as to how to best manage the situation. I'm sure in time they will get along like a house on fire, but I think these early days are important especially with how me and my OH respond to Jimmy's reactions to Lilly.
Also any tips on teaching Lilly not to chase the cats as she as already shown interest in them. It has been 8 years since we've dealt with a puppy and Jimmy was a dream pup (and admitedly we spoilt him rotten, we sure wont do that again!) so some fresh idea's would be wonderful
