My dog is red around his mouth. It’s come up in the last 24 hours and he definitely hasn’t eaten anything red. Should I be worried?

Thanks for using Petco Pet Education Center, formerly Petcoach. This could be a contact dermatitis or sensitivity. This is especially likely if Russell had started using a plastic food or water bowl in the last month. If so, switch back to ceramic or steel. There are also auto-immune diseases and allergies that can affect this area. If there is no improvement in one week or if worsening in any way, please see your vet for a closer examination and possible treatment options. Best wishes to you and Russell.

It looks like Russell's skin is irritated, and this could be from allergies. It could also be that he has a skin infection. I wouldn't be overly worried about it, but it is something that should be checked out by a vet. Give his vet a call to make an appointment to have this examined, diagnosed, and treated. Best of luck, I hope this helps.

That looks like an allergic reaction. I would give him TWO of the 25mg benadryl capsules and see if that helps to reduce these lesions by the morning. If not, then I would get him to your vet for an exam. Other possibilities: 1. Superficial dermatitis - skin inflammation/infection. 2. Autoimmune disorder like lupus. He would need some testing to figure that out if your vet thinks this may be the case. 3. Furunculosis - deep bacterial infection of the follicles. 4. Tumors - possible but not likely. I hope this helps. Best wishes!
