She may have something stuck in her mouth. Check the roof, cheek pockets, under the tongue, teeth, etc.
Dont let her eat grass give her the rolled up bread instead.
She can have pepto, pepsid, kayopectate or any OTC at www.wolfdancer.org/health scroll down for products and dosages.
She may have a bad tummy ache. I would pick up any dog food.Try a small amount of boiled chicken with all fat drained off, chop meat , or baby food with no onion, beef, turkey, etc add cooked white rice or infant rice cereal.
Go very slow so she does not throw it up.
Dogs get dehydrated and hypoglycemic very easily.
Add unflavored pedialyte to her water 50/50 to hydrate her and balance her electrolytes.
Put a drop of pancake syrup on her tongue to raise her blood sugar in case she is a bit hypoglycemic. That should perk her up.
Keep her on that very light diet of boiled chicken or chop meat for 48 hours after she is backk to normal.
Also give her one teaspoon a day of plain yogurt to keep "good" bacteria in her system.
If she develops any abdominal pain, bloating, constipation or cannot keep anything down she needs to be seen by a vet.
Please let me know how she is doing. I will always be here for you
I hope your baby feels better very soon..
