My puppy was bitten. Why is he sleepy and has a bump on his head?

Head trauma is always a cause for concern. Since this happened yesterday, there should have been some improvement with your pup if he suffered an injury such as a mild concussion. Sleeping a lot is not so much of a concern since young puppies normally sleep most of the day, but if you also see signs such as unresponsiveness, a head tilt, circling while walking, unequal pupil size, twitching of the eyes, ataxia (wobbly gait) or [vomiting](https://www.petcoach.co/dog/condition/vomiting-1/) then he should be [seen by a veterinarian immediately](https://www.petcoach.co/article/how-to-handle-a-pet-emergency/). If there is a bump, it may be a seroma (blood filled sac). This can treated by your veterinarian by either draining the area or trying a veterinary anti-inflammatory medication. Do not medicate him with anything OTC without the advice of your veterinarian as [many OTC drugs can be toxic](https://www.petcoach.co/article/7-human-medications-that-are-dangerous-for-your-pet) to dogs.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Wallace. He's biting the area because it's bothering him. This could be a cyst, benign growth, malignant growth, or lipoma. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give his vet a call to make an appointment. Best of luck.

The bumps could be an allergic dermatitis from fleas, insect bites, etc. It could also be a bacterial infection, even if you aren't seeing any purulent material. You could bathe him with a dog shampoo, like Epi-soothe, and see if that helps. Otherwise, he should be seen by a vet for treatment. He may need an antibiotic, anti-histamine, corticosteroid, of other medication to help.

That's quite a lump! If it is growing rapidly or is painful, then Smoke should be seen by your veterinarian or at the nearest veterinary ER as soon as you can get him in. The same can be said if he is lethargic or unresponsive. If he is behaving normally and the lump is not bothering him, you can wait until tomorrow morning to have him seen by your vet.

Hi Seth! Molly is a lovely looking girl. This pustule could be from an insect bite, it could be a cyst, or she could have injured herself causing it. It is concerning that she is acting lethargic lately, and I would have her seen by a vet first thing in the morning for it as long as she is still eating and drinking, and going to the bathroom normally. The vet can diagnose what is causing this pustule and lethargy, and can treat her for it. If she isn't eating or drinking, is extremely lethargic, or develops other signs such as vomiting and diarrhea, I would take her into a vet immediately. I hope this helps!

I'm sorry Sally is not feeling well! The large blister definitely looks like it can be caused by an inset bite and is painful, but it is also concerning that she is lethargic. I recommend having her looked at by a vet as soon as possible, in case there is systemic toxicity from the bite.

It is usually cause by hitting the head on something hard or bu an insect bite. monitor it for 3-4 days to make sure the swelling is going down, if it doesn't please take him to your vet in order to get it checked.
