It does not at all sound stupid.

I also have a 8 1/2 year old male collie (Whiskey) who has always been agressive to children and I did seek for advise when we had our baby.

I understand your situation perfectly as when Whiskey came to me at 7 months, he had severe rachitism and the vet told me that it was very hard to cure him. But with our efforts and him being very young then, he eventually did. At 2 years of age, he had something at his tail and we had a biopsy which resulted as a lymph tumour but we once again got over it. He is now 8 1/2 years old and remains as my best companion.

My sincere suggestion is, your pal has lived his life and at his old years. Anything could be expected just like you could expect from a 90 year old human. But he loves you, and would like to have you by his side. And I understand that you are taking care of him very well. Try to feed him, with anything that he would take.

However, loving you, if it is not very severe, he will not express his pain to you. You will have to observe him. If he is in deep pain, and there is no cure, I would suggest (as an approver of eutonasia) you to releive him from pain - do not like to express the phrase.

Hope all will be well.
