I saw this kind of rash on my chocolate lab last night, it’s in the crease of his back legs. The spots do not seem to be bothering him. He’s not licking or scratching at them. We live in the country but both of my dogs are treated for fleas and ticks every month like clockwork. My other dog (also a chocolate lab - they are litter mates) does not have anything like this.

I checked him over and don’t see any sign of fleas or anything else on him. I also don’t think they look like flea bites from what I looked up online. I’m thinking maybe an allergic reaction to something? I am going to call the vet and take him in but they are closed on Tuesdays so I can’t do that until tomorrow. Like I said, it doesn’t seem to itch or be sore. I only know it’s there because he rolled over playing with a toy and I saw it.
