What causes small spots on my puppy's snout? When to see a vet?

If the spot has changed in size over time it wouldn't hurt to have your vet take another look at it, especially if the change was very rapid over the past few days or weeks. Your vet may recommend taking a sample of the spot for testing to help determine what it may be so it can be treated as needed. Growths like this can be caused by any number of things including rubbing the spot often on surfaces, cysts, blisters, allergies, etc, so having it examined if it is changing is best.

Those two spots look like ingrown hairs or perhaps infected pores. Generally these lesions are benign and will go away on their own. You can try washing them daily and rinsing them well or your vet may carry some medicated wipes. Because they are on the muzzle topical ointments generally aren’t a good idea as the dogs will lick them off. Make sure to keep the food bowls cleaned on a weekly basis as well as any chew toys. I hope this helps and please feel free to post any additional questions.

I would have that checked out by a vet. This lesion is concerning for certain fungal and parasitic lesions that can get much worse if left too long. I also worry about skin cancer in white-faced dogs, so it will be good to have this ruled-out as a potential cause. No need to panic, just get it checked out in a day or two. For now, you can keep the wound clean by blotting it with a cloth soaked in warm water. Do this twice a day and avoid scrubbing.

I am sorry to hear about your concern for your pup. This looks like papules or a miliary dermatitis. We could see these from a variety of causes ranging from parasites of the skin such as mites, to allergies, to bacterial infection. If the spots aren't going away on their own in a day or two I would recommend an exam at his vet to help determine the cause of the lesions which will guide the treatment.

This could be due to an autoimmune disease but it is very hard to say just by looking at a photo. I suggest you have your dog examined by your vet as soon as you can get an appointment. It's not an emergency but sometime in the next couple days would be good.

It is possible that they are small wounds/ scabs from the puppies playing rough with each other. I commonly see play wounds on puppies. However, other possibilities such as skin infections, ringworm, and mites are all possibilities. Best of luck and enjoy your new puppy! Thank you for using Pet Coach!

That are certainly weird looking! Depending on when those lesions started and if they seem to be itchy, my presumptive diagnosis might differ considerably. It is possible that Cami might have been sticking in muzzle in an area that she shouldn't have been, resulting in some sort of irritation, and the lesions you currently see. They do definitely appear to be red, inflamed, and possibly infected based on the picture. Another possibility is that there is an immune-mediated condition that could be the cause of this. There is a disease known as Pemphigus that is known to cause skin lesions near the nose. I would definitely take Cami into the vet to have these areas assessed, and have some preliminary diagnostics run on the affected portions of the skin. Hope this helps!
