Hi John,
Try mixing the amount of Probiotic powder that is recommeded in a bowl with 10-15ml of water, swirl around water in bowl to dissolve the Probiotic powder then let your dog drink it as a treat same time daily inbetween meals..

It’s best to take Probiotic when stomach acid are low with no with food, not when stomach acids are high to digest food…
There’s a really good f/b group called,
“Dogs with Inflammatory Bowel Disease IBD – Raw Feeding & Holistic Support” group
They recomend using Goats Milk, Kefir & Probiotics, the goats milk will help your girl gain some weight.. you dont have to fed a raw diet..
