My dog has a movable lump near his penis. Is it a tumor?

I have noticed about a week ago that my dog has a bump/swollen lump next to his penis. it is not very big, oval shaped. It is the colour of his skin and no discharge occurred. This bump a week ago was noticed after he got groomed. My dog is doing eve

Thanks for using Boop by Petco! This could be a benign or malignant growth. 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. While this could be something benign, there is a possibility of it being malignant which is why it needs to be taken care of. I am really hoping for something benign. Good luck and have a good day!

My dog has a two lumps small lumps under it skin and moves about. what is it

Thanks for using Boop by Petco! These could be benign or malignant growths. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have your pup evaluated by a veterinarian for further assessment and treatment. Good luck and have a good day!

Paisley has a lump on her right side next to her nipple. It’s very soft and doesn’t seem to cause her any pain. Is this something to be concerned about? Is it possibly a tumor?

Thanks for using Boop by Petco! This is in fact likely a tumor or growth. This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance.

I’m trying to figure out what this mass is under my dogs legpit area. It’s grown over the last week but not sure how long it’s been there. I believe it wasn’t there last month so it’s pretty new.

My dog is 5 years old and about 3 days ago these lumps appeared on his testicles. I’m really worried and I was wondering if I should bring him in? The first photo was from Saturday and the 3rd one was taken Monday.

Hi my dog is a chihuahua and she's had these bumps on her stomach for a long time now, it doesn't seem to grow nor bother her when we rub her stomach but I still want to look into it. Should I be worried? Do you have an idea of what it could be?
