Hi there. Bumps like the one on Bear could be a few different things. Sometimes there can be a thorn or something else stuck beneath the skin causing the bump. It could also be a skin growth, examples of these are things like epitheliomas, mast cell tumors and lipomas. Because it's red and is causing him some irritation, I would recommend having your veterinarian check the bump. They may suggest doing a fine needle aspirate of the bump, which collects cells from within the bump to help diagnose what it is. It's not an emergency, but I would have it checked when you can. I hope that helps! Thanks for using Petco Pet Education Center, formerly Petcoach!

    This could be a growth, from an injury, an infection, or a foreign body. This is definitely something that needs to be checked out by a vet, so I'd have Max seen by one in the next few days. Best of luck.

    Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. It could definitely be a small bug bite, or even a pimple or an ingrown hair, although it doesn’t look very inflamed. Since he was recently groomed, he could have gotten knicked by the clippers in that area, making it slightly reddened. As long as he doesn’t seem bothered by it and it isn’t painful to the touch, and he is otherwise healthy, I don’t think he needs to go to the vet right now. I would recommend monitoring the spot to see if it changes in appearance at all (color, size) or if more spots appear anywhere on his body. If this occurs, Cash may need to be evaluated by a veterinarian who can examine the spot more closely and determine if it has become infected. I hope this helps!

    I'd keep an eye on this area for now, it doesn't look too big or red in the pictures. It may be an area of irritation but it can be a sign of a skin infection. Should this area get redder, bigger, Ava has hair loss, or it starts to bother her, have her seen by a vet. I hope this helps!

Any idea what this might be on my dogs inner thigh?
Hello, sorry to hear about Bear. Its difficult to tell exactly what that is without looking at the structure and what makes up the little nodule. That is, the cells forming the little nodule would need to be evaluated to tell exactly what that is. Given that it is a small area, it could be removed and submitted to biopsy to determine the cellular make up. Alternatively, you can monitor to see if the nodule resolves. If it goes away within a few days, then this is likely nothing of big concern. More severe things this could represent such as cancerous tumor can begin by looking like this. If this is indeed something more aggressive, then it may continue to grow and get worse. If so, then this should definitely be evaluated by their veterinarian. Please keep a close eye on this nodule, it should begin to improve within a few days, otherwise have your this further evaluated by your veterinarian. Hope this helps and best of luck.

There is a red bump on my dogs back around his butt and it looks like something bit him maybe but we aren't very sure it has puss coming out of it he has been scratching at the spot for about 3 days but we just noticed the spot it is a hard spot and
If there is pus coming out of it, I would be inclined to think that this bump on Bear is an abscess. It would cause him pain, and also cause him to be lethargy. I would take him into a vet either now or first thing in the morning to have this bump examined. If it is an abscess, it will need to be drained and flushed sterilely, and he will need antibiotics to treat the infection.

what is this on my dogs thigh it’s filled with blood
This looks like it could be a hemangioma, which is a benign 'blood blister' type skin lesion, or it might be an insect bite or site of previous trauma. It would be a good idea to have your vet take a look in person if it has not resolved in the next week or so or if it seems to be bothering Bear.

What is going on with my dog bears boy parts. He keeps chewing on it. He has little red bumps on the other side but not as bad. He squats when pees mostly in the bushes
Hello and thank you for your question about Bear. Unfortunately the picture is blurry so I can't get a good idea of what I'm seeing. It looks red and circular but I"m not certain. In general, a sudden red spot or rash could be several things including fleas, allergies, skin mites, bacterial infection, ringworm (which humans can get) or endocrine disease. There are a couple things you can do at home and they can help but they may not address the underlying cause. You can try adding in an omega 3 fatty acid supplement for dogs, this can help improve the skin health. You may also try changing his diet to something like Royal Canin or Nutro as they are aimed at skin health. You can wash the lesion(s) once a day (not his whole body, just the lesion). Also protect the area from trauma by having your pup wear an elizabethan collar at all times. If the lesion does not start improving within a week or if it is getting worse, have him examined by the veterinarian. I hope this helps an

Hi! Around 3 months ago I catched my dog Balder from the streets after running out on the countryside. He is estimated to be around 1 year old maybe a bit less. About a week ago I noticed a small bump next to his penis (but no attached to it) which I
Thanks for using Boop by Petco! This could be a benign or malignant growth. This could even be an infection site. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

a little bump under the skin of dogs ear flap behind the ear.
Thank you for contacting Boop by Petco with your question about Bear. This bump could be a benign or malignant growth. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give his vet a call to make him an appointment. I hope this helps!

Hello, For 6 days ago I noticed a lump/bump on the back of my dog's thigh. At first it was only pink and raised and then it had changed in the following days. It has become more red and it looks like there is only a thin layer of skin over her flesh
It could be a small cyst, pustule/papule, or possibly a Histiocytoma which is a benign mass that is common in young dogs. Since it is getting more red, she should be examined by a vet to determine the cause. The vet may want to aspirate it and examine the contents under a microscope. She may need an antibiotic, anti-inflammatory, it may need to be removed, or just monitored (histiocytomas typically resolve with no treatment). You could use an over the counter spray, like Vetricyn, and see if that helps relieve any redness or discomfort.

My dog has a red bump on her belly. What could this be? She seems fine, it doesn't bother her.
It could be an infection of a hair follicle, or it could be a tumor of some kind. I don't see her age listed, if she's very young its unlikely but it it is possible. If its not bothering her, it is not an emergency, but get her in when you can. Your vet may take an aspirate (poke it with a needle and look at the cells under a microscope ) to get a better idea of what it is, or they may recommend surgical removal if they are worried about a tumor, or an oral antibiotic if it seems to be an infection. Thank you for asking Boop by Petco.

Hey I’m puppy sitting my moms friends puppy and there are some concerns I have under her thigh there appears to be red bumps almost bites?? And I just wanna know if i should be concerned for my dog
Hi there and thank you for using our consultation service. I really appreciate your providing us with pictures. The good news is that those bumps or lumps are not an emergency situation right now. as long as your dog is eating and drinking completely normal, I would just simply alert the owner of the dog of these bumps. tell them that this could be possible dermatitis or growths that need to be checked by better near in as soon as they have time. I would urge them to not wait longer than one week after the owner gets home to take them to the vet for a complete dermatological examination. Thanks a lot for your question. I hope I have given you some help.
