Hiya Mary,
I'd be interested on replies to this thread to, as you know I have the same problem with Buttons.
Although, have seen a change in the last few days.
The reason is Roana, Roana = competition
After looking after Roana my friends cocker since Thursday night, i have seen a remarkable change in Buttons eating habit. So far she has eaten everymeal put down to her
(being JWB & tripe mix)
The dogs are not competitive as such over food, no growling, food guarding and are quite happy to swap bowls half way thru. But I do think that there is more pressure for her to eat as otherwise Roana will eat it for her
Gilly
