2 Jack Russell's
Hi I have had a Jack Russell since being a pup and she's 8 now. In may I took on my dad's Jack Russell who is 5 after his death. Both are female and previously got on together. They are ok together but growl at each other and appear to do this only when I'm home. They don't growl or bark when it's just my husband at home. It's like having 2 toddlers! How do I train them to be nice to each other more??
