Gettys Dog Skin Rash Mouth


My female Labrador is just under 2 years old. She has developed a strange rash around her lips and mouth. She has been chewing a lot lately, but I thought maybe that was due to her being in heat.

Last night I had a chance to get a real good look at her lips and I am worried now. There has been a change in dog food from Eukanuba to Merick. The other dogs in the house seem fine and unaffected.

Also she is a field dog and a water dog. She loves the water. She was reverting geese 2 weeks ago, at which time I can not recall if her mouth was or wasn't like this.

Editor Suggestion Dog Skin Rash around mouth and Dog Lips

Dear Jason,

It is a little difficult to tell from your pictures, but it looks like your Lab also has some skin issues on the rest of her body, not just around her mouth.

To know exactly what is going on, you would need to take her to your veterinarian for some diagnostic testing: probably a skin scraping to look for mites, a fungal culture for ringworm and cytology to look for bacterial and or yeast infection to begin with.

Sometimes it is cheaper in the long run to get a definitive diagnosis as soon as possible.

That said, there are a few things you could try at home first as long as she is doing well otherwise. First, since her skin problems coincided with a change in diet, I’d switch her back to her old food, just in case she is allergic to something in the new food.

Next, bathe her with a dog shampoo containing chlorhexidine (such as Duoxo) twice a week for the next couple of weeks. This could help control yeast and bacteria on her skin as well as remove allergens from her coat.

Finally, if she is current on heartworm testing and your vet is willing to prescribe Revolution, I’d give her that to kill and fleas and sarcoptic mange mites.

Good luck,

Jennifer Coates, DVM

rash around lower lip

Could changing her to trifexes from confortis and the brown heart worm pill thay she has been on since a puppy cause the rash, such as an allergy?

Just this month on the 19th I decided to try it. Also, be advised I tried this product when she was much younger and she scratched a lot from itching. I put her back on the confortis and heart worm pill she stopped scratching.
