I am so sorry for your loss. It is so painful to experience. I have 2 young Yorkies and also have never left them anywhere. I'm nervous that they won't take care of them correctly
Whenever I've gone anywhere lately, I made sure they could come along. I search for 'pet-friendly' places online. It is so valuable to have someone you can trust to leave them with! I'd LOVE someone like that! Welcome to YT and (hugs) for your lost pup.
