My dog won't eat, has a fever, and is weak. Should I see a vet?

Hi and thank you for using Petco Pet Education Center, formerly Petcoach. I recommend that you take your dog to see a veterinarian. It sounds like he needs immediate care if he is not eating, he is lethargic and may have a fever. This sounds like a serious condition that needs to be addressed sooner rather than later. Your veterinarian will perform a full physical exam and determine what additional testing may need to be done (xrays, bloodwork) to give you a better idea of what treatments are needed. Good luck.

I would get your pet seen by a vet as soon as possible. Fever and loss of appetite is concerning and should be investigated. There could be any number of causes, but a sudden onset fever usually indicates an infection of some kind that should be treated with medication right away.

Thank you for submitting your question regarding Winnie. Yes, I recommend that she sees a veterinarian if she is still not eating and drinking. I worry that she will become dehydrated being such a small dog. Based on her exam findings, treatment can be recommended or diagnostics if necessary. For example, fluids can be given under the skin to rehydrate her and anti-nausea medication to control any further nausea and vomiting. I hope this information helps!

Betty sounds very sick at the moment, and based on her symptoms, she should see a vet immediately. Without seeing her in person, I can't say what's causing her fever, lethargy, weakness, and lack of appetite, but she could have a systemic illness or infection causing it. She does need veterinary care now for it, so please bring her into a vet right away. I hope this helps!

I am sorry Queen isn't feeling well. Since she is not eating and acting weak, I would not give her more time, I would get her to a vet right away. They need to check for parasites and parvovirus. Bring a fresh stool sample so they can check her out and get her treated. Good luck and kisses to Queen!

It sounds like Code is sick. I am concerned he hasn't eaten for a day and he's weak. Not eating can be a sign of many problems such as dental disease, systemic illness, infection, or injury. Without seeing him in person, I can't say what is going on. I'd have him seen by a vet today to get this diagnosed and treated. Best of luck.

For a dog that usually eats well, 5 days is getting a little long to let it go. I would recommend that you have Panda checked out by a vet to see what could be going on. There are so many things that could be causing his vague symptoms, including pain, infection, intestinal issues (including obstruction), among many others. After physical examination and a thorough medical history discussion, your vet may recommend treatment, bloodwork, or x-rays to see what could be going on.
