My dog is itching after dust exposure. How long will symptoms last?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Small (up to 22lb) | Male | neutered | 8 months and 24 days old | 12 lbs

Rupert has been scratching and biting at himself for two days now very often. No new diet, environment etc. We broke down and gave him 1/2 a Benadryl (10mil). This seems to help relieve his itching. Also hasn’t pooped really in few days, on little bits. He has also been shedding. (Not typical for a Morkie). Only thought would be that he spent one afternoon “helping” us clean up a dusty/dirty room. How long can I expect this to go on if being out of a dusty environment was the cause?

It can last 2-3 days in some cases, in others it can last 2 weeks or even longer, each dog can react very differently and it really depends how sensitive your dog is to dust, if dust is the cause at all.
