Why is my dog's tail gland visible or swollen? Is it serious?

The most common reason that we will see what you are describing if it is close to the anus is an anal gland rupture. I am attaching more information about anal glands below. https://veterinarypartner.vin.com/default.aspx?pid=19239&id=4951501 I would recommend having your veterinarian examine Kye to make sure the area doesn't need to be flushed. We most commonly treat these with antibiotics and pain medication. Good luck! I hope that was helpful. Thanks for using PetCoach.

Yes, I would be concerned this may be serious, especially if it has grown quickly. The broken surface is very high risk for infection and I recommend an urgent assessment by your vet; biopsy and possible tail amputation may be required. In some male dogs, a hormone dependent condition can cause similar masses and castration can be helpful in these situations

Unfortunately, I can't tell from the photo what is happening exactly. It sounds like Charlie needs to be examined by the veterinarian and I recommend to have that done today. Anal glands should never protrude. Abscesses and cancers are both possible if the gland looks like it is protruding. Both of these need to be addressed by the veterinarian. You may need to have someone take him to the vet for you or see a local veterinarian. Charlie should also wear an elizabethan collar at all times to prevent him from licking and traumatizing the area. I hope this helps and please feel free to post any additional questions.

This is likely her anal gland that is inflamed and infected and likely to rupture. There are anal glands found on every dog that are just inside the rectum roughly at the 4 and 10 o'clock position that should empty on their own when your pet poops. However, some pets have a hard time doing this, and these will fill up and become infected. You will need to take Copper to your vet soon to have these flushed out, lanced, and then he will need to be placed on antibiotics and anti-inflammatory medication. I hope that your pet Copper gets this resolved soon. Talk with your vet about getting his anal glands expressed regularly at the vet to hopefully prevent this from happening in the future. Best of luck to you both. Take care.

This looks like an infected cyst. Dogs have a scent area on their tails that can enlarge and get infected such as this. You can apply a hot compress to the area several times daily to see if it will drain. That will increase the blood supply to help it heal faster. Bringing Ben in for an exam would confirm a diagnosis and they would probably prescribe antibiotics which would lessen the healing time. This doesn't look like a mass to me, so it should resolve quickly with treatment. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Ben.

Some experts may say 4 and 8, while others may say 3 and 9. The lump in the image does not appear to be located where the anal glands are. Ideally, you should have Lucky examined by your veterinarian. If this is not possible, monitor the lump for rapid change, growth or discomfort. If you see any of these changes, he will need an exam.

That protrusion is from her vulva. Molly needs to be examined by the veterinarian. It’s possible there is an infection or a mass which could be cancerous. The veterinarian will get a better idea once the area is palpated. Have her examined today. Best of luck.
