Skin and coat changes in older dogs and cats
Your pet’s skin and fur do a lot! They protect vital organs, regulate temperature, and battle the elements. But as your dog or cat ages, you may see signs of it on their skin or coat. We’ll take you through those changes and tell you how to help.

Do older dogs have more skin problems? How about older cats?
Many skin conditions in dogs become more common with age, including infections, hot spots, and shedding problems. Skin conditions in cats often involve hair loss, oily fur, or irritated skin — especially in long-haired seniors. This is because as they age, their skin can become more delicate, and their immune system can become weaker.
Some common signs of aging include callus formation, graying of the fur, and a duller and/or thinner coat. These typically aren’t cause for concern, but it’s always good to mention them to your vet just in case.
Beyond common signs of aging, skin conditions in dogs and cats can include constant scratching, constant licking, redness, discharge, bald patches, scabs or open sores, pustules or rashes, crusty, greasy skin, scaliness, or lumps and bumps (more info on lumps and bumps here).
These symptoms can point to injury, infection, parasites, allergies, or something else. It’s important to take your furry friend to the vet at the first sign of these symptoms so they can advise on treatment and get your pet feeling better as soon as possible.
Call your vet if you notice these skin conditions in dogs or cats:
- Sudden hair loss
- Open wounds
- Bleeding or oozing skin
- Lumps or bumps that change in size
- Skin that smells bad or seems painful
Here’s how to help treat skin conditions in your older dog or cat
Since many different things can cause skin and fur issues, it’s important to get your senior pal to a vet. They’ll be able to do an exam and recommend any further testing to help figure out what’s plaguing your pet.
Treatment options typically include everything from medication to diet changes.



What to know about shedding in senior dogs
Excess shedding is sometimes seen in senior dogs. This can be a normal sign of aging, or it can point to one of several other issues, such as:
- Hormonal issues
- Parasites
- Bacterial infection
- Nutritional deficiencies
If you notice drastic hair loss, thinning fur, or bald spots, contact your vet as soon as possible.
Do older dogs get more hot spots? How do you treat a hot spot on a cat?
Hot spots are a common skin infection seen on cats and dogs. They have several causes, but essentially are the result of itchiness leading your pet to scratch, lick, or chew on themselves. This creates open sores or bald patches that we refer to as “hot spots.”
To treat a hot spot on a cat or dog, you’ll want to get to the underlying cause of the itchiness with your vet. They’ll likely prescribe a topical medication and instructions on keeping the spot clean and dry.
Please don’t attempt to use a home remedy on your pet’s hot spots — or any skin or coat condition! These are often ineffective or end up making the condition worse.
Support your senior pet’s skin at home
- Use year-round flea and tick prevention
- Brush regularly to remove dead hair and check for issues
- Use vet-recommended shampoo
- Avoid over bathing your dog
- Monitor any changes in coat texture or skin appearance
