Problems around a dog’s bottom are more common than many people realise, and while they can look worrying, most are not urgent. That said, some conditions do need quick veterinary attention, so it’s always best to get advice if you notice something unusual.
Bottom problems can cause discomfort, pain, or irritation, and dogs often show this through changes in behaviour rather than obvious signs. If you’re unsure what’s going on, your vet can help identify the cause and get your dog feeling more comfortable again.
There are many possible reasons a dog might develop a bottom problem. Some of the most common include:
Intestinal worms can make a dog’s bottom itchy and uncomfortable, sometimes leading to scooting. In heavier infestations, worms may cause blood in the poo. It’s unusual to see worms in poo unless they’ve already been killed by a worming treatment.
Dogs have two small anal glands just inside the anus. If these don’t empty properly, they can become blocked or infected.
Blocked anal glands often cause itching, irritation and scooting, while anal gland abscesses are usually very painful. If an abscess bursts, you may notice blood, pus or open sores around the anus.
Male dogs have a prostate gland, which sits just inside the bottom. Prostate disease can cause pain, difficulty pooing, and changes in urination, such as peeing more often than usual.
This is an uncommon but painful condition that mainly affects German Shepherd Dogs. It causes deep sores to develop around the anus, which can bleed and be very uncomfortable.
Lumps or swellings around the bottom can interfere with pooing and cause irritation or pain. Any new lump, or one that is growing or changing, should always be checked by a vet.
A rectal prolapse happens when part of the rectum comes out through the anus. It appears as a red, tube-like structure under the tail and is often linked to severe straining. Rectal prolapses are rare but are an emergency and need immediate veterinary care.
In female dogs, it’s important to check whether the problem is coming from the anus or the vulva (the entrance to the vagina).
Conditions affecting this area include vaginal prolapse, which appears suddenly as a large, red swelling, or pyometra, a serious womb infection that can be life-threatening. Dogs with pyometra may have vaginal discharge, drink more than usual, and start vomiting.
Contact your vet if you think your dog has a problem with their bottom or back end. Even if it doesn’t seem urgent, it’s always better to get advice early. If you’re having a phone or video appointment, taking a clear photo of the area can be helpful.
