My new neutered puppy is lethargic and won't walk. Is he in pain?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 2 months and 4 days old | 5 lbs

Hi, I recently adopted a puppy from a shelter. They do neuter/spay on all of their animals. The puppy is male and about 2 months old. Yesterday was the first day we had him. He was as playful as a puppy can be, but today he is acting different. Laying down he will nibble and play, but he doesn't want to walk a round the yard or house at all. I don't know if the shelter gave him pain meds, but could the lack of pain meds post-neuter be the cause? He was neutered 3 days ago.

I am very sorry to hear rhay Spock is not acting very energetic. I believe it could be because one of the following reasons; Spock could still be adjusting to the change in his life. The last couple of days have involved a surgery and a new home and family. All of this may take time for him to adjust to. He might feel slightly insecure and could benefit from some of the following techniques to help him adjust; Extra walks Extra interaction time - petting, and games Special meal of boneless boiled chicken breast and white rice It is possible that Spock is still in pain or that the surgery site is not healing well. Look for swelling, redness, heat, pain or discharge in the area. That would indicate infection. If you notice any of those signs, you believe that Spock is uncomfortable or not healing well take him into a veterinarian for a check-up. It's usually a good idea to have a new family pet addition examined by a veterinarian within the first month anyway. Best of luck with Spock!

    Yes he may be painful if he played hard when he was just neutered. Please make sure he is eating and drinking and the incision looks closed and not red. If he seems otherwise fine keep him quiet, let him rest and take him only for short leash walks for a few days. Do not give human pain medication. If he is unwell please take him for a veterinary exam. He should be fine in a few days.
