Why does my senior Great Dane's hind end suddenly smell so bad?

Thanks for using Petco Pet Education Center, formerly Petcoach! It is hard to see any detail in the picture. However, it does look like there is an infectious process going on. This may be in the skin per se or possibly in the anal sac region. I would recommend that you have him evaluated by a veterinarian for further assessment and treatment. They would be able to diagnose it so that it can be treated. Best of luck!

Different odors have different causes. A foul odor may indicate a bacterial infection. A yeast infection sometimes smells like Fritos. A fruity smell can indicate ketones created by diabetes. Dental disease also has a strong smell. Anal gland "juice" smells fishy. If you can't figure out where the odor is coming from, I would have Muffin examined by the vet.

Thank you for submitting your question regarding Bentley. I recommend that he sees his veterinarian. He may have overly full anal glands, an anal gland infection or even a skin allergy affecting his hind end. The veterinarian will examine him and try to determine how best to treat him. In the meantime, place an E-collar on him to prevent him from licking the area. I hope this information helps!

Your dog may have infected or impacted anal glands. This certainly would explain the discomfort and foul smell. I recommend getting him seen by your vet as soon as possible to have them checked to make sure that is indeed what is going on, expressed and maybe put on antibiotics to help him heal faster.

Hello. It sounds like Aramis may be suffering from an anal sac infection. The soft swelling would be present just off to the side of the anal opening...either on right or left. He may continue to ooze smelly fluid out of the anal sac opening which is just inside the anus. These abscessed are painful, itchy and can eventually rupture leaving a draining home in the skin. Aramis needs to see a vet to have the infection drained and for the anal sacs to be emptied. This may require sedation as it can be quite painful. He should then be prescribed an antibiotic. Your vet will probably want to recheck the area in a couple of weeks as these infections are stubborn to get rid of sometimes. Thank you for using Petco Pet Education Center, formerly Petcoach.

Hello, sorry to hear about Daisy. One thing is that she could have impacted anal glands that could be leading to an abscess. Second is that she could have perineal fistulas, an autoimmune disease that could cause the foul smell. I would recommend having her evaluated so that she can have her anal glands and perineum evaluated to treat any underlying infection. Hope this helps and best of luck.

Thanks for using Petco Pet Education Center, formerly Petcoach! It looks like you have done everything you can to help with this at home. However, this may be due to impacted or infected anal glands that may need veterinary evaluation and treatment. I recommend that you have him evaluated by a veterinarian for further assessment and treatment. They would be able to diagnose the issue and treat it accordingly. Best of luck!
