1. 12 pounds (he's a large pappy, not overweight)
2. We haven't given him Benadryl lately because it doesn't seem to work. we have given him children's and adult. We either squirt a children's dose into his mouth or crush half an adult capsule.
3. We use Frontline flea control and just applied some 3 weeks ago.
4. No. Our vet (who just passed away) told us about the grass allergy because Reg licks the bottom of his paws a lot.
Thank you. We're pretty sure he has no back or hip problems - he's extremely active and shows no signs of pain when running, fetching, etc Are the medicines you mentioned antihistamines - zyrtec, chlopheniramine? Should we try a hypo-allergenic diet? Please tell me what the "hills z/d" diet is. We feed him Blue Buffalo dry and wet food combined, with added bran since he's become somewhat constipated as he gets older.
If we decide to try the antihistamines, what dosage is appropriate?
