My 14 year old dog who has skin cancer started to throw up last night qnd now he isn't eating. He threw up for times and

I see that your dog is vomiting and not eating. I am sorry to hear he has skin cancer.

Some more information may be helpful. Do you know what kind of skin cancer he has?

Is he getting treatment for the skin cancer?

How much does he weigh? What is his name, by the way?

Thanks for the information. For vomiting and appetite, you can try giving him Pepcid AC/famotidine. It is over the counter in stores and pharmacies. He can take 20 mg twice daily.

Some types of skin cancer, such as lymphoma or mast cell tumors, can spread internally and cause symptoms like vomiting and loss of appetite. I hope that is not the case with Valentine, but if he continues not to eat, I would have him checked by his veterinarian.

You are welcome. I am sorry he has this cancer that keeps coming back. It wold be best to find out if that is related to his vomiting and not eating.

Please let me know if you have other questions and what you find out.

Hello; this is Dr. Rebecca checking in to see if you have other questions. How is Valentine?

Thank you for the update. I am glad he is eating and drinking now.

I hope he continues to do well.
