Got a 7 week old pup, had him indoors for 3 days and tonight decided to move him into the kennel. I put him in and the bitch 4 yr collie whippet grey growled at him... I picked him up and brought them both indoors, the bitch growled and then went for the pup. Shes never been like this with any other dog and has been kenneled with other dogs before. I really dont know what to do. Any ideas?
