My dog's anus is red, swollen, and wet after grooming. Is it serious?

Red’s anus does look irritated and I can see some redness on the underside of his tail as well. He might be licking due to irritation from full anal glands, parasites or allergies. I would recommend having your vet examine him and check his anal glands. They may want to check a stool sample as well. Oral or topical medications might help. I would recommend putting an e-collar on to prevent licking until you can get to the vet.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely due to an infection of the anal sac or possibly allergies for example. I highly recommend that you have him evaluated by a veterinarian for further assessment and treatment. Best of luck!

Thank you for providing pictures of Madden's anus for me to see. From the pictures, it could be that he has a rectal prolapse, or he could have impacted anal sacs causing this redness and swelling. The best thing to do is take him into a vet as soon as possible. The vet can diagnose what is causing this redness and swelling, and can treat him for it. Good luck, I hope this helps!

This looks like a mass adjacent to the vulva, and it is probably not related to the recent grooming. This could be a benign mass like a lipoma or could be something more serious, and I would recommend taking her to your veterinarian to have it examined. They may want to take a small sample using a needle. Another possibility would be a hernia, although this is a little less likely based on your picture, but a veterinarian would probably be able to determine whether or not a hernia is possible based on an exam.

Honestly, it could be either from these photographs. If she's not scratching or dragging her bottom and the puffiness is the only symptom at this time, I would keep an eye on it. If it doesn't improve or resolve in a couple of days, I recommend getting her seen by your vet for an exam.

It does look like the area to the right of the anus is irritated. Dogs have anal glands besides their anus, so if Loki has been scooting, that may be an issue. I am attaching a link with more information about anal glands below. http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=625 I would recommend having your veterinarian examine Loki and check his anal glands. Certainly, Loki could also be having a skin problem, so if his anal glands are normal, then your veterinarian can look for a skin infection to see if that may be the problem. Good luck! I hope that was helpful. Thanks for using Petcoach (now Boop).

Oh dear, poor Sadie! Her skin issues coupled with the redness and swelling of her anus and vulva could be due to underlying allergies to fleas, food or the environment. I see that she has not been spayed, so it is also possible that her vulva is red and swollen if she is going into heat. The anus can be red and irritated from parasites or anal gland issues, as well. At this point, I recommend assuring that Sadie is receiving a high quality flea preventative (such as Nexgard, Bravecto or K9 Advantix II). You can try bathing her in a gentle oatmeal shampoo or antimicrobial shampoo, but she will likely need to go to her vet for an exam. The vet will be able to assess her changes and determine if a skin infection is present as a result of her ongoing itching. She may need to have a course of antibiotics and anti-itch medications to help resolve this issue. I hope that all goes well!
