My new TM Betty (~10wks) shares a house with two ~2yr old Vizslas (quite a crew, right?) and they tend to rough-house pretty hard. Betty has ZERO fear of the larger, older dogs and I can't really tell how much to let them 'go at it' and establish their roles as older, more alpha pack leaders (the V's) or if I should be stepping in to try to mellow out the TM. Am I teaching her dog aggression or am I teaching her how to "get along"? The V's definitely put her on her back and are very 'gentle', but I just don't know what I am perpetuating here- learning or bad behavior. Any input is welcome!
