Pekingese dogs tend to have very sensitive skin. If you observe your Peke having a skin allergy, you must treat it quickly in order to prevent further discomfort and to save the dogs coat. Once a Peke gets an itch, they tend to bite and gnaw away until the hair falls out and they wind up with bald patches and painful hot spots.
The most common cause of skin allergy among Pekingese dogs is fleas. Both the dog and the dogs bedding need to be treated in order to get rid of the problem. The best way to do this is with a monthly treatment that is applied to your dogs neck and works for 30 days. You may have to try out a few different brands to find one that works best for your dog. Often, rotating through a few works well.
Another, newer, alternative is to give your dog a monthly treatment by mouth ( Trifexis). We have been using this treatment since we had a baby (don’t want her touching the poison on the dogs fur!) and it’s been great, however, it does not protect against ticks so if your dog likes to run in grassy areas you may want to either use a collar or a topical, in addition.
Even if you treat your dog regularly, you may want to limit her exposure to other animals (cats, dogs) that may carry fleas and even dog parks.
Depending on the severity of your dogs allergy to fleas, your vet may prescribe a topical spray to sooth the itching and speed healing, and in the most extreme cases a steroid, taken by mouth, may be prescribed as well.
Naturally, if you have other pets in the house, they should all be routinely treated for fleas as well.
If an itch is accompanied by vomiting or diarrhea, most likely it was something that your dog ate which he is allergic too. If this is the case, provide your dog with plenty of water and limit his food intake. Also, take a look around the floor in places where food scraps may have fallen and clean up anything laying around.
