Occasionally after spaying, dogs will have no appetite for the first 12-24 hours. This may be due to the lingering effects of anesthesia and/or some post operative discomfort. If she still has no appetite two days after spaying, I would be concerned that she may be in pain or there may be another underlying concern affecting her recovery. Call your veterinarian to discuss your concerns. He or she may recommend a recheck, and some more pain medication. In the meantime, take a look at her incision site. If it is red, swollen and hot to the touch, she needs to see your veterinarian right away as these symptoms may indicate infection. You can also try offering her a bland diet of boiled chicken and white rice or some treats to stimulate her appetite.

No, it is not normal. Did your vet provided pain killers? If not, pain might be the reason, take her back to your vet tomorrow morning for an additional checkup.

Offer her some treats and see how she's doing today. If she's not seeming to be feeling better by tomorrow, take her to your vet to be rechecked. Its not unusual for their appetite to be decreased for a day or two after surgery.
Thanks for asking Petco Pet Education Center, formerly Petcoach!

I'm sorry that Snowball is feeling a little off after her surgery. I would check to see if her incision is hot, red or swollen. There are multiple reasons she could be not eating as well, including pain/discomfort, a side effect to a medication or an underlying disease process unrelated to her surgery. I would contact Snowball's regular veterinarian to have her evaluated and any treatment that may be necessary.

Yes, I would be concerned about this behavior from Shelby. While it is good that she otherwise seems like her normal self, it is concerning that she has lost her appetite. I would offer her a bland diet of boiled white meat chicken (no bones) and white rice for a couple of days, then slowly add back in her normal diet. If she still refuses to eat her normal diet, stops eating altogether, becomes very lethargic, stops drinking water, or starts vomiting, then I would have her seen by a vet.

My puppy is throwing up and won't eat 3 days after spay. Normal?

It can be normal to vomit once or twice in the 24 hours following anesthesia but I wouldn't expect Sadie to be experiencing side effects from anesthesia at this point. I would recommend having your veterinarian examine her if the vomiting and decreased appetite continue: it may or may not be related to her recent surgery. If she is on a non-steroidal anti-inflammatory pain medication like carprofen or meloxicam it would be best to discontinue the medication since these can sometimes cause stomach upset - your vet can prescribe a different pain medication if necessary.

My dog isn't eating much after spay surgery. Is this normal?

The onesies may be uncomfortable or stressful for her. Try taking them off at feeding time. Watch her closely though so she doesn't get to her incision. You can also warm her food slightly or mix in a teaspoon of plain baby food to stimulate the appetite.

My dog isn't eating and has diarrhea 3 days after spay. Vet visit?

Thank you for submitting your question regarding Luna. I do recommend that she sees a veterinarian today. Her incision appears to be healing well. I do not see redness, swelling or discharge draining out. However, pictures can be deceiving. I am more worried that she is not eating. The diarrhea needs to be addressed as well. The veterinarian will examine her and take her temperature. A fever, for example, can indicate an infection. If you stopped her medications, which is reasonable given the diarrhea, she may be very painful now though. This too can affect appetite. The veterinarian will guide you on any testing or treatment options. In the meantime, keep her quiet, encourage her to drink so she doesn't become dehydrated and do not give any over-the-counter pain medications as these can be toxic to dogs. I hope this information helps!

My spayed cat is not eating, lethargic, and has strange stool.

After 3 days, the recovery from anesthesia should be gone and she should be feeling like her old self and normal. For her to not have an appetite at this point is concerning something else is going on and it is not part of the surgery recovery. I would recommend taking her to a vet for a check up. They can take her temperature and make sure she is not dehydrated. They can see if there is an infection or a virus that is making her feel bad. Continue to do broth or you can try tuna or the juice to encourage her to keep fluids in until you get her seen. I would also try to keep the other cats away from her so she can rest.

My dog eats more after spay. Is increased appetite normal or should I feed more?

Thanks for the question. No, it isn't normal to have an increased appetite after being spayed. It is possible they are eating more due to stress, but I can't say for sure. As long as their weight is stable, I do not recommend increasing the food. It may only be a temporary increase in appetite, but you will want to monitor for any other changes. I hope this helps.

My cat is lethargic and not eating after spay. Is this normal?

I'm not sure how long ago Xenon was spayed, and while you would expect some lethargy and decreased appetite the first 24-48 hours after surgery, the cat should start to perk up after that time. If it's been 48 hours since her surgery and she is acting this way, I'd take her into a vet now to get checked out. Best of luck.

Why won't my dog eat 5 days after pyometra surgery? Is it normal?

This is not normal, so I would be somewhat concerned. I would be more concerned if she was also vomiting, had diarrhea, and/or a decrease in activity. Some pain medications can cause side-effects in the stomach and usually have directions not to give these when they are not eating. Make sure to double-check the medication labels for these warnings. If Diamond goes longer than 24 hours without eating, then I recommend contacting your vet. I hope that helps and Diamond gets better soon.
