My dog lost weight, not eating after pet died. Grief or illness?

Pet's info: Dog | Golden Retriever | Male | neutered | 8 years and 4 months old | 50 lbs

My dog is eight years old. We had a dog that this dog was really close to but he passed away. Before he passed away, my dog started losing weight. After he passed, my dog lost a lot of weight much faster. He also has only been eating half of his portion. Is there a relation to this or is it another medical issue?

Thanks for using Petco Pet Education Center, formerly Petcoach! While the worsening in weight loss could be related to the loss of your other pet, the fact that there was already weight loss makes a medical issue more likely. There are plenty of conditions that can cause weight loss such as inflammatory diseases, intestinal malabsorption, cancer, among many others. I highly recommend that you have Elvis evaluated by your veterinarian for further assessment and treatment. They would be able to gather more information and start with diagnostics such as radiographs, blood work and a GI panel. So sorry for the loss of your other pet. Good luck and have a good day!
