My dog is lazy and not eating after illness. How to make him active?

Poor Pocholo! It definitely sounds like he isn't feeling well for some reason. Unfortunately, these symptoms are very vague and could be caused by almost any type of illness or injury, so there's no way to say what might be wrong without being able to examine him. I would recommend taking him to the vet for a check-up as soon as you are able to - he/she can do some blood work or other testing if needed to help determine what's wrong and get him started on appropriate treatment for the problem.

Thanks for using Petco Pet Education Center, formerly Petcoach! Lack of energy can be the sign of many things that go from just being tired to actually representing a problem like due to pain for example. If he is otherwise fine, I recommend you keep a close eye on him for now. If there is no improvement within the next 2-3 days, have him evaluated by a veterinarian for further assessment and treatment. Good luck and have a great day!

I'm very sorry that Summer is not acting herself. Unfortunately, her symptoms are very vague and don't point to any one illness or disease process. Pretty much anything can cause lethargy and not eating. I strongly recommend you have her examined by your vet to help figure out what is going on with her especially if it has been a few days already.

At 3years of age he would generally expected to be more active but every dogs character is different and some are very placid. If his behavior has changed over the last 3 months I strongly recommend a full health check by your vet to rule out medical or painful conditions which may be reducing his mobility

withhold food for 12 hours then offer Poppi boiled boneless chicken and rice every 6 hours in small portions. if he is eating and not vomiting, continue with this diet for 2 days. After 2 days, you can put him back gradually on his normal food. If Symptoms do not resolve or get worse, take him to the vet to get treatment.

I'm very sorry Sadie isn't feeling well! I can understand they you might be worried, but it is a good sign that she is eating every meal and drinking water. Lethargy is a very general sign of illness, and it can be caused by many different things such as systemic illness, infection, injury, or inflammation. I would monitor her for now, and if she is still lethargic in 24-48 hours, I would take her into the vet for a health check.

Given the lack of clinical signs besides lethargy and inappetence, there is not much else to go on here. I would consider obtaining a rectal thermometer tomorow and checking for a fever (above 102.5), which might suggest the presence of an infection or inflammation. If you detect a fever, I would definitely suggest getting Rusty to the vet sometime soon. If there is no fever, but his condition does not get better by Monday he should be taken in for an examination regardless. You can certainly try and feed Rusty something that would normally be considering irresistible just to see if he will accept it, rather than just his normal dog food. Anyway, hope this helps and that Rusty is feeling better soon. It is entirely possible that he might just feeling a little under the weather or maybe could have eaten something he shouldn't have that upset his stomach. If this is the case, the symptoms should pass with short time.
