Can dogs get seasonal allergies?

yes most if not all dogs have allergies just like people

This can be a very important part of managing atopy. While it may be impossible to completely eliminate all of the offending agents, many can be reduced with minimal effort on the part of the owner. For avoidance therapy to have any benefit, the offending agents must be identified through intradermal skin testing. Avoidance is rarely a complete treatment in itself, but is used in conjunction with other treatments. Allergen Avoidance Suggestions House dust House dust mites Molds Pollens Keep pets out of room several hours when vacuuming Change furnace filters regularly Use a plastic cover over pet's bed Wash bedding in very hot water Avoid letting pets sleep on stuffed furniture Avoid stuffed toys Keep pets in uncarpeted rooms Run air conditioner during hot weather Change furnace filters regularly Keep pets out of basements Keep pets indoors when the lawn is mowed Avoid dusty pet foods Clean and disinfect humidifiers Use dehumidifiers Avoid large numbers of houseplants Keep dogs out of fields Keep grass cut short Rinse dog's feet off after dog has been outside Keep pets indoors during periods of high pollen counts

Yup. It's actually pretty common for puppies actually. Some outgrow it, but not all. First you'll have to rule out that it's not food based (did you recently change his food?) because puppies are especially sensitive to changes in diet. I know my shepherd is allergic to something in certain types of dog food, and itches almost constantly if she's been eating it - it makes her halter bother her so much that she used to shudder when I put it on her. If that's not the case, then you need to take it to the vet. They will be able to tell you what would be the best thing for you to do to ease your dog's symptoms, and be able to rule out any sort of parasite or illness.

Yes they can. My vet told me to try giving my dog a Piriton anti allergy tablet once or twice a day as it can help alleviate symptoms. (piriton available from drug stores).

I believe they can, because my dogs skin gets very red and irritated and itchy during season changes.

yes dogs could get the seasonal allergies
