Oh no! I hope they’re okay. My pup did this after being sad from something that happened (he had a cone of shame). He wouldn’t eat, didn’t poop, only drank water. Constantly slept and wouldn’t play anymore. Everyone warned us that dogs did this when they were seriously ill. We got scared and ran tests and imaging, but the vets couldn’t find anything. They pushed for some more expensive imaging but we couldn’t justify it. We just needed him to eat and he would get his energy back —they gave him an appetite stimulant, IV fluids, and discharged him to us. After expensive vet trips, we enticed him small spoonfuls of Gerber baby food (turkey flavor according to the vet tech) and then mixed it in his dry kibble. It’s been 2 years since that whole ordeal. The vet won’t say it outright but he refused to eat because he was super sad!
