My dog (10) just recently started to lose appetite, has trouble getting up, moving really slow, doesn't come to the front door when I arrive home, and became really weak. I've been telling my parents that this is an emergency and we should take her to the vet now but the closest appointment is 3 weeks away. I know that I shouldn't give up on my dog but I want to prepare for the worst while hoping for the best. I want to know if anyone else has experienced a passing of their beloved pet and how they coped.
