I have treats that she likes. I dehydrate liver and cut it into small pieces, which she loves but she has a sensitive tummy and she only puts so much in to it. Then she just turns her head away. After that she will work but she does it for praise(and to go with me) not treats.
She spent yesterday with vomiting and liquid poops. We started her on Pepto per the vet. This calmed the gut. Then late last night she got hypoglycemic. I had to rub White Syrup on her gums to get sugar in her. Thank God the vet tech lets me have her cell phone number to call in case of emergency. Then she ate a small meal and today is droopy but not like yesterday.
I always panic when one of the fur babies gets sick.

I to have a self trained service dog who has a sensitive tummy. For loose stool I use canned Pumpkin, 1 tsp/15 lbs of body weight mix in the food. Works great. Make sure it is just pumpkin no sugar or additives.
Good Luck.

Lindecker01,

You said to use pumpkin for the runs, but how much do you give a 5 1/2# Chihuahua? can't be much more than a taste. We raised the pups to never eat table food, they get a good brand of dry puppy food and semi-moist treats and all the rawhide they want.

My female never gets the runs, but her brother does about every two months...it lasts 2-3 days and then he's fine but it doesn't affect his appetite. He has bad separation anxiety sometimes and will vomit if he knows I am leaving without him, or if he thinks I am going without him....weird pup. They are 16 1/2 months old and well into their service training as hearing assist dogs.

Out in public they are all business. If we have company, I put their harnesses on and buckle the chest strap, but I don't tighten the rest....the harness means time to settle down and behave....they will either stand in front of everyone and look like angels, or they will go to their cushion and lay down.

Bearbear started alerting me at 10 1/2 weeks to people coming up behind me.
He pokes his nose into my arm and looks over my shoulder. They both go shopping with us and are just as mellow as can be...and after calling the health dept. we take them to the local restaurants, and its okay for them to sit in the booth with us, since we can't see what they are signaling if they are under the table. The health dept. said all that has to be done, is when we leave for the waitress to use a rag with some bleach water and wipe off where they were sitting. There is one place that is really cool about the pups when we take them....they have tables with 4 chairs and the pups get their own chair, and they patiently wait through us ordering and eating...they have never tried to get on the table, we've taught them not to beg...when we get ready to leave, I give them a treat and they are ready to get back in the van.
