Hi Cass: did you mean JULY 5-12? Whatever, I sincerely hope you have a wonderful time in Cuba. I wish I could convince you and your Mom that you did more than 99% of dog owners would do for their dogs. You should have NO guilt, and no what ifs. It takes awhile for grieving to take its various forms, and you just have to go through them.
I have had a number of dogs (being 81) and a while ago, I started having two. I had 2 Irish Setters, one a granddaughter of the other, two ex-racing greyhounds, a pit mix with another mutt. Both of those were from my vet. And of course the chihuahuas. I have had 5! Two of them now. I have one chi now, who at 11 is having heart issues and when she passes, I really don't know if I'll get another chi or not. If I decide to get another one, I probably will get an older one from rescue.
Thanks for updating us. Have fun in Cuba.
