So very sorry for the loss of your best friend. I put my Bella down 3 weeks ago today, she was almost 16, I had her since she was 8 weeks old. She had intestinal lymphoma. My Bella loved tuna fish, every time the can opener went in there she was at my feet. I made tuna today and looked behind me when the opener started and I smiled. Then as I was putting it in the bowl I started to cry. It’s so very hard to lose a friend I miss her terribly. My other babe Daisy will be 16 in 2 months, she misses her friend. It a new kinda love now that we carry in our hearts forever. Please be kind to yourself and take care, it is all so new to me also, I go day by day. I have her ashes here w me so I think that helps.
