My new puppy has a belly rash. What could it be and is it serious?

Our puppy that we got 3 days ago has a rash on her belly. We think she had it when we got her but we just didn't see it. We are in the process of finding a vet, but are wondering what it may be?

Congrats on your new puppy, but I'm sorry Sasha has a rash! Thank you for the picture, it's very helpful. This could be puppy pyoderma, which is a skin infection. Puppies have very sensitive skin, and they can be prone to bacterial skin infections. Puppy pyoderma is quite common amongst young puppies, is usually not serious, and can easily be treated by your vet. Another cause could be fleas. I can't make a definitive diagnosis without seeing her in person, so it's good you are trying to find her a vet. Finding her a vet is not only good for this problem, but also for getting her vaccine course completed, making sure she is healthy now and in the future, and having there for any potential problems that may arise. Once you find a vet, please make an appointment for her to be seen to get this diagnosed and treated. I hope this helps!

    It can be difficult to tell from a picture but it looks like a common skin infection in younger dogs. It can be referred to puppy pyoderma. I would recommend taking him to a vet for a good exam to make sure it is just a mild skin infection and get proper medication for treatment. thanks for using pet coach. hope that helps

Got our new puppy yesterday. After making it back home with her at 5 in the morning (16 hour round trip to get her), we noticed these whiteheads all over her belly. At first I thought, "just heat rash," but these seem to have more puss in them than I
Congrats on your new puppy, but I'm sorry Birdie has a rash. It could be puppy pyoderma based on the appearance of her skin in the pictures and the location of the rash. A puppy's skin is very sensitive, and this is especially true in areas where there is lack of protective covering of hair. Puppy pyoderma is a bacterial skin infection. Treating it requires a course of antibiotics which you do need to see the vet for to get a prescription. I would recommend having her seen by the vet sooner than May 1st for this problem, and I would call the vet in the morning to see if you can get her in sometime this week. Best of luck, I hope this helps!

My dog has red rashes on his skin mostly in the lower belly region and beneath fore limbs but sometimes also on the upper body and neck. He has been facing this since mid February the temperature usually rises and becomes hotter. He eats kibble and h
This could be a condition known as puppy pyoderma. It's roughly the equivalent of acne in adolescent humans. It usually clears up as your puppy gets older and there isn't any treatment needed unless it gets really bad. If so, get him in to see your vet and they can prescribe antibiotics and topical treatment as needed. You can bathe him with a mild, oatmeal-based shampoo for dogs and lukewarm water to help clear the rash and soothe his skin.

My dog currently has a very mild case of a rash on her stomach. She is an 11 week old puppy I have thoughts that might be impetigo.
Thank you for contacting Boop by Petco with your question about your puppy. It's likely puppy pyoderma, which is a skin infection. Puppies have very sensitive skin, and can be prone to infections. I'd have her seen by a vet in the morning to have this treated. Best of luck.

Why is my dog having belly rashes and stopped eating?
It could be puppy pyoderma, which is a skin infection, causing the rashes. As for not eating, that could be due to many things like teething, systemic illness, infection, inflammation, or injury. I'd take Kai into a vet now to get both these things checked out.

Hey, my puppy has a rash on her stomach that as far as I can tell developed in the last couple hours. She doesn't seem irritated or anything and isn't scratching it. But it doesn't look good. Any ideas?!
She could be having an acute allergic reaction to something such as grass or some type of chemical on the ground. You can try washing her off using a mild cleanser such is Dawn dish soap or oatmeal-based pet shampoo. If it doesn't clear up within 8 to 12 hours then I would recommend having your veterinarian do an exam. In the meantime if you start scratching or itching at it you'll need to stop her as that could cause a secondary bacterial infection.

My dog has these spots (and some other marks) on her belly near her genital area. They just turned up a few days ago, aren’t irritating her, aren’t red or bumpy or crusty. Just a flat bald spot in a perfect circle, some have peeling edges. She’s othe
Hi, thanks for using Boop by Petco! Poor Sasha! It's hard to tell in the picture. The 2 pink areas look like scars. But describing them with a scaly crust around them sounds like a skin infection. I think it is fine to watch for worsening before taking her to the Vet. If you notice small white heads or red bumps then that likely confirms a skin infection and she should be seen. You can try the below shampoo and bathe her twice weekly leaving the lather on for 10 mins before rinsing. I wish Sasha the best! https://www.drsfostersmith.com/product/prod_display.cfm?pcatid=27306

My puppy has a little rash on her belly near her vagina. What are some natural things I can do to get rid of it? Also she had brown spots. Are they normal?!
I’m not sure if the lighting makes the skin look normal in your picture, or if the rash you are describing is faint enough to not show up on the picture, but her skin appears fairly normal to me. The brown spots I see are normal pigmentation variants. Often times mild skin problems in young dogs are bacterial and bathing in a shampoo that has chlorhexidine or salicylic acid can be helpful. These can be found in the human shampoo aisle in the dandruff area. If it does not seem to help then I would encourage you to have her evaluated by your veterinarian soon. Best of luck and thank you for using Pet Coach.

My dog is a 12 week old German Shepherd and she has puss-filled pimples on her belly. Is that something I should be concerned about or is it something that will go away in a few days?
Congratulations on your new puppy! We commonly see a skin infection in puppies that we call "puppy pyoderma". It is a skin infection of the normal bacteria on a puppy's skin. Every case is different. Sometimes we need to treat them with topical wipes or shampoos, and sometimes we prescribe oral antibiotics. I would recommend having your vet evaluate Emma and decide on the right treatment plan for her. I have included a link to general pyodermas below. The difference in a puppy pyoderma is that there is not normally an underlying cause that we need to find. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=1571 I hope that was helpful. Thanks for using Boop by Petco.

So I recently adopted my dog from my coworker so she wouldn't have to take her to the animal shelter. Recently she has breaking out on and off on her stomach but today was the worse I've seen it. It doesnt itch because she is not scratching but I hat
That looks quite uncomfortable. I'm surprised that she isn't super itchy. I don't see any obvious causes in the picture - such areas that make me suspicious of a bacterial or yeast infection. My top guesses be allergies (flea, food, environment, or even a contact allergy such as being allergic to your laundry detergent), with skin parasites or a superficial infection definitely possible. Since it's such a large area, it's going to be hard to apply an ointment - if you have a medicated bath for another dog (one that is for superficial infections) that may help. Wiping the area with witch hazel could calm in down. A mild (1%) hydrocortisone cream could also calm down the area. I would definitely recommend getting her to the vet as soon as possible. They are likely to need to do an exam saying she's in good health before she can be added to the insurance, and she's not going to qualify until her skin is better.

I recently noticed what appears to be a rash on my puppy's stomach and back legs. What could be the cause?
Puppies have very sensitive skin, and that can leave them prone to skim infection. I suspect that Willow has puppy pyoderma (a skin infection). You need to have her seen by a vet to have this diagnosed and treated.
