My dog has a red spot under a scab. Is it a bug bite or allergies?
Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. She definitely could have gotten a bug bite in that area that caused her to itch/bite at that area, creating a scab. If it is the only small area, I'd say a single bug bite is more likely than something like allergies, which tend to affect a diffuse part of the body. As long as she is acting normally at home (not continuously itching, and she is eating/drinking normally), I recommend monitoring her at home. You can check that site daily to see if it is getting smaller and less red. If you notice that it is getting bigger, or you notice the development of more similar spots, or she is licking/biting at it, I recommend having her seen by your veterinarian. I hope this is helpful - best of luck with Precious!
