I am sorry your boy is not feeling welll
Shaking can be due to pain, fear, nausea, stress, etc.
You can give him one mg of benedryl per lb of his weight.
He 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
Dogs get dehydrated and hypoglycemic 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. That should perk him up.Keep him on that very light diet of boiled chicken or chop meat for 48 hours.
Also give him one teaspoon a day of plain yogurt to keep "good" bacteria in his system.
If he develops any abdominal pain, bloating, constipation or cannot keep anything down he needs to be seen by a vet.
Please let me know how he is doing. I will always be here for you
I hope your boy feels better very soon..
'Small dogs get hypoglycemic very easily. Your baby should eat more than a morning meal and a snack at night. He may be getting acid reflux because his tummy is empty.
Try to feed him a small meal when you go to bed. add a half of a pepsid a/c tablet to prevent acid reflux.
If he is still shaking something may be hurting him or he may be nauseous.He coud also be hypoglycemic so try a drop of syrup in his mouth. You can try the pepsid now if he has not eaten breakfast yet.If you have any chicken or chop meat you can boil for him that will be much better than dog food.
Please let me know how he is doing
