My shih tzu is 1 and off her food. She's drinking water.

Customer Question

My shih tzu is 1 and off her food. She's drinking water. She's sleeping lots. I took her to the vet last Thursday and they excised a 'scab' from her fur under her neck the vet described as ecsema possibly caused by a bite (insect). They gave her short and long acting antibiotic injection. Now she's up and down in herself and not eating.

Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

What antibiotic was she on? Is she still on it?

Can you tell me if she can keep water down?

What did her vomit look like?

Are her gums pink or white/pale?

If you press on her belly, does she have any tensing, soreness, discomfort, or tenderness?

Could she have eaten anything she should not have (ie toys, bones, socks, rocks, plants, people medication, toxins, etc)?

She had an injection of short and long acting antibiotics last Thursday...don't know which one.
She's not been sick at all.
She doesn't have any tenderness. She just wants to be left alone to sleep and isn't interested in food.

Thank you,

Now the reason I asked about her antibiotics specifically is because a number of them can cause nausea as a side effect. And if we have a low grade nausea lurking, that can cause appetite loss and lethargy.

Therefore, since she has none of those sinister signs I asked about and wasn't likely to have eaten something odd, we'd want to consider taking some steps to settle her stomach at this stage. First, I would note that you can consider putting her on an OTC pet friendly antacid like Pepcid (More Info/Dose @ or Zantac (More Info/Dose @ After that has had some time to absorb, you can try tempting her with a light diet (ie rice with boiled chicken, white fish, cottage cheese or scrambled egg). Whichever you offer, do only give small meals a few times daily to keep her stomach settled.

Overall, with her history and recent treatment, this would be our main concern here. Therefore, we'd want to try the above and monitor her closely. If she doesn't respond to this, then we'd want a recheck with her to make sure there are no other issues afoot and have them treat her stomach upset woth an injectable anti-nausea treatment.

I hope this information is helpful.

If you need any additional information, do not hesitate to ask!

All the best,

Dr. B.
