Hi Tanya,

if she is throwing up I would take the vet food back to vet office for a refund or exchange, tell receptionist what is happening & can you try a different brand WET vet diet, the receptionist will go & see vet & ask him, you shouldn’t have to pay again for another vet visit..
ask can you try the Hill i/d™ Low Fat Canine Rice, Vegetable & Chicken formula,
it Reduces risk of urinary stone formation, has OK ingredients & is LOW in fat, Shih Tzu are prone to pancreatitis, I wouldnt be feeding a 10 yr old a high fat diet maybe the vet diet she is eating is high in fat or she could be vomiting cause she has only ever been fed the one food her whole life, I always recommend to rotate between a few different brands so immune system strengthens, plus some dry dog foods are high in toxins, heavy metals & contaminates especially the fish dry foods..
Here’s the Hill I/d vet diet to try just till you work out what your doing & stop her vomiting.

Which vet diet was she put on
Royal Canine S/O Urinary wet & dry or
Hills C/d Multicare wet & dry formula’s?

She should be on a wet vet diet not a dry vet diet…

I’d be contacting a Vet Nutrionist & ask about making a home made balanced wet diet, or you can contact “Balance It” they have nutritionist who prepare special diets & you add Balance it powder to balance diet.

also are you adding Vitamin C Powder to diet?

Vitamin C for Prevention of Chronic Urinary Tract Infections in Dogs

Have a look at “D-Mannose” Pure Powder alot of people say its really good you also add cranberry powder aswell.

Also follow “Dr Judy Morgan”
look thru her video’s link below,
I’m pretty sure her 17 yr old dog has urinary problems & she cooks for him, her recipes are very easy. Even if you feed 1/2 cooked diet & another food…
