When I had my pup spayed, I found an inflateable e collar at Petco. Spookie was 5lbs at that time, a hard collar just would not have worked. She is a Maltese.

My Aussie was allergic to spring. He got Benadryl.

Your baby may have inhaled allergies. Think carpet, smoke, house things. Try a grain free food. Pricey, but may help. Or go poultry free food, including treats.
