Allergy symptoms for dogs typically involve the skin as much as the respiratory system, even if the dog has inhaled the allergens, rather than had direct skin contact with the substance. Allergies to several kinds of substances cause similar symptoms for dogs, but you can often narrow down the cause. Only a licensed veterinarian can give a definitive diagnosis of any particular allergy; however you can usually determine on your own if a grass allergy is a possible cause of your dog̵6;s symptoms.
Instructions
Observe your dog̵7;s symptoms during the spring growing season. If your dog develops rashes or respiratory problems after you or your neighbors have mowed a lawn, he might have a grass allergy. According to halopets.com, dogs who are allergic to airborne pollens (including grass) may develop itchiness around the face, feet and armpits.
Check your dog̵7;s skin after he has been lying in grass. Contact allergies won̵7;t always appear immediately, but if your dog was lying in the grass on his stomach and develops a rash there, he might have a grass allergy. It̵7;s also possible, however, he is allergic to fertilizer or other chemicals on the lawn, rather than the grass itself.
Watch your dog for other symptoms of pollen allergy, as described by canismajor.com. These include head shaking, face rubbing (against the ground, floor or your furniture) and biting, licking or chewing at his skin. These symptoms may not be from grass--they could be from another pollen--but if he does this each time after an afternoon jaunt in a grassy park, consider grass allergy.
