Rash on toddler face

Destiny

Hey guy’s my son has this rash going on his face its on both sides and he has a bit on stomach as well im not sure what this is. I have already called pediatrician but im waiting for them to give me a call back. Has anyone experienced this? We just got a dog about a week ago im not sure if this is an allergic reaction to the dog or something else. 🥺
