Grew up as a child with a retriever and doberman in the family.
Aunt is a guide dog 'puppy walker'.
We lived with my partner's Mum and brother for a few years. Brother had a Westie, Milly. She was not 'ours', but she was very much part of the family and came over regularly to visit and stay for 'holidays' once we had moved out.
We lost her early last year to lymphoma. Vets tried their best and we had a few extra months, but towards the end it was becoming clear that treatment wasn't working and quality of life was suffering. I got to see her one last time a few days before that painful decision had to be made.
Unfortunately, I also got to find out about her passing via FB, which I was less than pleased about.
We have to hold on to the good memories.
I don't have any advice as to your next decision, but I'm sure your gut will tell you what is right and when.
My words to FB...a few days later, once the dust had settled - apparently I was in the wrong for feeling aggrieved I found out the way I did...
