Oh, she was... They were just outside playing again, and I saw the first sign of a problem -
Daisy was playing with her Wobbler, and Cole started looking interested/jealous...
Up until this point, he has REFUSED to eat anything that was purchased for her - kibble, liver treats, cheese treats, dog cookies, etc. Well, I pulled her back and knocked over the Wobbler, and he came over and ate the kibble that came out of it. I put her back down and she continued getting her breakfast, but as she played the Wobbler got closer and closer to Cole... When it got right up in his face, he started growling at her
Cole has food guarding issues, so I knew in getting her that she can't be around him when he's eating. I didn't, however, think about it being a problem feeding HER in his presence. I guess it makes sense - Cole is extremely selfish/greedy. I don't entirely blame him for that, as he was literally starving to death as a puppy when we took him from the neighbor's yard. His mother had been eating dirt to try and produce milk for the pups, and the pups were trying to survive on dirt/leaves/roots.
It was really interesting to note that, while Daisy was playing with the Wobbler, Cole lay down in the dirt and started nibbling at the mud and the roots. My poor boy has residual issues, it appears.
At any rate, now I know to put the Wobbler away before the puppies can play!
