I see you are a pet behavior consultant - Might you answer a question or two?
1. Female golden retriever has, since birth, acted as if she is covering something in her food bowl. She will do this before, during, and after a meal. She has literally rubbed all the black off her nose which is now pink.
2. We started making their (we have the female (7) and a male (8)) dog food about 4 months ago. She scarfs it down and she does not hang around to "cover" it like she used to do the Science Diet we previously fed her.
OK, that is it. If you lived her in the states you could ask me something about home financing, since that is what I do, but since you don't I do not know how I might be able to reciprocate for your answer.....
