Lobito is so cute! It sounds like he had an infected anal sac that opened up, and you did exactly the right thing by taking him into the vet. Antibiotics should help clear up the infection, and there is a chance the anal sac can heal on it's own. Without seeing it in person, I can't say for certain, but definitely keep an eye on it and if it doesn't appear to be healing over the next week, have him seen by a vet again as then surgery may be needed to close it completely. Good luck, I hope this helps!

Usually once the gland has ruptured, and I think that's what you mean when you say it opened up, they don't require surgery. The surgery for an uncomplicated (i.e., first or second time it's happened) anal gland infection/impaction is to lance the gland with a blade while the pet is under anesthesia, drain the contents of the gland, then flush it and usually instill anti-inflammatory medications into the empty gland.

If this is a chronic problem, it's possible the Lobito will need surgery to remove the gland. This is necessary when the duct leading from the gland to the anus gets blocked and scars. Hopefully this won't happen! I would say this only happens about 15% of the time.

My dog has a ruptured anal gland. Is expensive surgery vital?

Hello. Most anal gland infections heal up quite nicely with medications & keeping the area clean. Unless there is a special circumstance involving Tia's glands, such as the area is just not healing, additional flushing & treatment is usually not necessary. See how she does after a week on antibiotics & if she is doing well, just continue the antibiotics. Thanks for using Petco Pet Education Center, formerly Petcoach.

My dog's anal gland ruptured. When will it heal and stop leaking?

It usually takes about a week for an anal gland rupture to heal, but that assumes that the dog is on appropriate antibiotics and that the infection inside is clearing. If you're only seeing clear fluid and not pus, it sounds like the infection is getting better. You can apply warm compresses to the ruptured gland (wet a cloth and microwave it for 45 seconds or so until it's warm but not hot) for 5 minutes 3 times daily. It's actually not a bad thing that the hole doesn't close up too quickly, because it give the normal duct a chance to return to normal (the swelling to decrease) yet the gland will continue to drain.

My dog's anal gland popped. How do I care for it and prevent issues?

This can be painful and messy so I recommend using a hot compress on the area several times a day to keep it clean and draining. Then I apply a thin film of antibacterial ointment on the surface. As Milo will lick the area using a cone or restraint collar to prevent licking will help it heal faster. Once the sac has ruptured it usually will heal quickly on its own. Continue the antibiotics until they are finished. To prevent this from happening again I would have Milo's anal sacs expressed regularly, every two to three months.

My dog's anal gland burst. Can I give Clavamox if I can't see a vet?

I usually send home Simplicef for anal gland fistula but Clavamox at an appropriate dose for Lily’s weight would definitely help, especially if you are not able to bring her to the vet right away. It is important to fully express both the ruptured anal gland and the other anal gland to prevent a second fistula on the other side. Ideally the ruptured anal gland should be flushed with a dilute chlorhexidine solution but a sitz is definitely better than not cleaning out the ruptured gland at all. I usually send home an e-collar to prevent licking, antibiotics, a probiotic to prevent antibiotic associated diarrhea, a nonsteroidal anti-inflammatory for pain such as Rimadyl, and a topical prescription steroid/antibiotic/antifungal ointment to speed up the healing process. Good luck!

My dog's anal gland ruptured. Can it heal at home without a vet?

Don't panic! Yes this will heal on its own. What I recommend you do is make a warm epsom salt solution and soak her little bum in the solution several times daily until the swelling goes down. She is small enough that you could put a 1/4 c of epsom salt in a kitchen sink-sized basin and have her sit in this until the water cools. This does a great job of healing the hole and drawing out the infection and swelling.

My dog has a painful wound near his anus. What home care helps?

Hi there, It sounds like Chico may have a ruptured anal gland, the anal glands on each side of the anus, but when they become too full they can burst and cause what appears to be a wound on the side of the anus. I would recommend trying to apply a hot compress with a warm wash cloth to the area, and keeping it clean, but he should start antibiotics prescribed by your vet to fight the infection. I hope that helps. Thanks for using Petco Pet Education Center, formerly Petcoach.

My dog's anal gland abscess burst. Should I use antibacterial cream?

Hello, thank you for your question about Abby. If the abscess has already ruptured and you are able to warm compress the area, I would recommend allowing it to drain and do not feel that it needs any topical treatment. Abby should be discouraged from licking at the area as this will predispose her to developing a secondary infection. You could purchase an e-collar at a pet store or try using a t-shirt at home. After the holiday I would recommend contacting your veterinarian and relaying this information. They may recommend starting a short course of antibiotics at that time to help Abby heal quicker and prevent development of an infection. They can also consider pain medication at that time. Hope this helps, good luck!
