My dog has a black discoloration on her face beside her mouth. Any idea on what could cause something like that? It’s only on one side no where else.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Discoloration around the mouth can be due to saliva staining. If Brownie has bad teeth, then she might drool more on that side causing more saliva staining. I recommend you have her seen by your vet to check if there is a wound present under the fur, or if she has dental disease that requires fixing. Best of luck with Brownie!
