Hello, sorry to hear about Rocky. It sounds like he is feeling unwell but these signs are non-specific. It may be caused by multiple reasons, most often a dietary indiscretion, ingestion of foreign material, or in puppies this young an infection with a virus or parasite may cause this. If Rocky is not eating by tomorrow, or if he begins to vomit, have diarrhea, or lethargy then he needs to be evaluated by his veterinarian immediately. You can offer him a bland diet tomorrow of plain white rice, skinless and boneless boiled chicken and cottage cheese low fat. Hope this helps and best of luck.

    Poor Rocky! If he does not want to eat and is starting to seem weak, he may be anemic or have some very serious illness going on. I recommend a vet visit right away for bloodwork and X-rays to identify what is going on with him and how to help him feel better. Sometimes autoimmune diseases like immune mediated hemolytic anemia can look like what you are seeing with Rocky.

    Thanks for using Petco Pet Education Center, formerly Petcoach! Loss of appetite can be observed with many conditions such as gastroenteritis, dietary indiscretion, kidney disease, pancreatitis, among many other possibilities. On the CBC (on the right side), I can see that Rocky has a mild to moderate anemia and mildly elevated white blood cells. These are relatively non-specific factors that can be associated with many diseases. The data on the left side I unfortunately cannot read as I do not understand the language. I recommend that you have Rocky evaluated by a veterinarian for further assessment and treatment. If he is not drinking water well, he should be evaluated by a veterinarian as soon as possible to prevent dehydration. They would be able to check for these possibilities and others depending on the findings on exam. Treatment would be based on findings. Good luck and have a great day! Hoping for a speedy recovery!

    It could be Rocky has a stomach illness, kidney disease, liver disease, diabetes, or even cancer causing his symptoms. Without seeing him in person, I can't make a diagnosis. I'd have him seen by a vet now to have this diagnosed and treated. Best of luck.
