Dog ate chocolate?

Red spot on dog's neck.

Species: Dog
Breed: Pug
Age: 1-2 years
I just noticed a red spot on my pug. I will try to attach a picture. It's on his back a little above his shoulder blades and about the size of a dime. His hair is coming off in that spot. It is a little raised and very red and crusty. Should I take him to the doctors?
I will email the photo of Thunder.
Thank you!

You mentioned when you sent the photo that you had recently applied a topical flea medication. I think that there is a good possibility that this is a reaction to that treatment.

Whether or not you take your dog in to see the vet depends on how bothersome the spot is. If your dog is not scratching at it then it may be ok to watch it for the next few days and see if it is improving. If it's getting bigger or starts to ooze pus at all then I'd take him in for a vet to look at it. However, if it is really itchy then he should probably have it looked at sooner.

Reactions like this are not common, but I have definitely seen them happen.

Hope things work out ok!

Dr. Marie.
