This will only cause a problem if the mole ingested poison or had bacteria.
A dog will eat grass in an innate atempt to solve a digestive upset. However, it can make matters worse by causing blockage.
Heaving can be a symptom of pain, nausea, stress or fear. Feel all over your boy and see if anything hurts him.Check inside his mouth for any bad teeth. Make sure nothing is sticking in his pads.
He may be in pain, scared and/or be nauseated or have stress..I would pick up any dog food.Try a small amount of boiled chicken with all fat drained off, cottage cheese, or baby food with no onion, beef, turkey, etc
Go very slow so he does not throw it up.
Dogs get dehydrated and hypoglcemic very easily.
Add unflavored pedialyte to his water 50/50 to hydrate him and balance his electrolytes.
Put a drop of pancake syrup on his tongue to raise his blood sugar in case he is a bit hypoglycemic. Do not allow him to drink a lot at a time If he throws up water, he can lick ice
I there is any swelling he can have 2mg per lb or his weight of benedryl.
He may have instead any human OTC at www.wolfdancer.org/health scroll down for products and dosages.
Keep him on that very light diet of boiled chicken or cottage cheese for 48 hours. Also give him one teaspoon a day of plain yogurt to keep "good" bacteria in his system.
.If he developes any adominal pain, bloating, constipation or cannot keep anything down he needs to be seen by a vet right away
Please let know if you still have questions and how your baby is doing, I will always be here for both of you.
I hope he feels better very soon.
