Why did my dog's fever spike in the car but is normal at home?

I’m glad to hear that he is improving on the medication. I would absolutely continue the prescribed medication and also schedule a follow up appointment with your veterinarian soon. They can discuss the medication and how long he should be on it. Best of luck and I hope he improves soon. Thank you for using Pet Coach.

If he is eating, nursing and taking the medication I am not sure why you are worried. I agree with what the other vet said. Don't stress him by continuing to take his temperature. You don't have to be worried unless he stops eating and/or nursing.

Normal temperature of a dog is 102.5 so her temp is just mildly elevated and could be caused by the stress and excitement of going to the vet. You could take her temperature at home and see if it elevated. Inflammation can could cause a mild elevation but I would be concerned if it increases and/or stays elevated. If she doesn't improve on the Deramaxx and the limp continues then your vet will need to do additional testing to determine the cause. An x-ray and blood work would definitely be recommended if she doesn't improve. Hope she feels better soon!

If your dog had been exercising or out in the heat it is possible his temperature could have increased due to this, but 104.1 is a pretty high temperature if you feel it was truly an accurate reading. We can see dogs temperatures get that high if they are really hot/excited/stressed and they are overweight or brachycephalic (smoosh faced) but I am concerned that his energy level was decreased. If he still doesn't seem himself tomorrow then I would bring him in for an exam. If overnight his temperature gets very high again, or he becomes weak, has trouble breathing, or his gums become pale in color or he starts having other symptoms like vomiting and diarrhea then I would consider bringing him in to the emergency vet.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Arielle. I'm sorry she is sick. Yes, it could be possible a dog has a fluctuating fever while on antibiotics. Fevers can be caused by viruses as well as bacteria, and antibiotics do not treat viruses, thus leading to the continued presence of a fever. If you are concerned about her, I'd have her seen by a vet. I hope this helps!

It sounds like Hero is starting to feel better based on your information. Swollen lymph nodes can be secondary to infection, inflammation or local disease. It is possible the antibiotics has helped the lymph nodes go back to normal size. Unfortunately with out additional testing like X-rays or aspirates of the lymph nodes it is hard to give you additional direction. I would recommend following up with your vet to make sure Hero makes a speedy recovery. I hope that helps

A fever this high is usually indicative of a bacterial or viral disease going on. Your veterinarian will need to run some tests to try and determine the cause of the fever. Once the cause is identified the proper antibiotics, antifungals, or antipruritic drugs can be prescribed. The tablet given to your dog is basically a fever reducer but will not treat the cause of the fever. I would recommend taking your dog in for a recheck as soon as you’re able to. The exact cause of the fever cannot be determined without further workup and diagnostics. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
