Overview
If your dog has loose fur and you can see more skin underneath, it’s often due to normal undercoat shedding. That said, it can also happen with coat change, rubbing, dry skin or an underlying skin problem, so it’s worth checking a few simple things at home first.
Things To Check
1. Check whether the fur is coming out evenly all over or in patchy areas, because patchy thinning is less likely to be simple seasonal shedding.
2. Look closely for redness, scabs, flaking, soreness, heat or any discharge on the skin underneath the loose coat.
3. Feel for mats, tangles or compacted undercoat, especially behind the ears, under the collar, in the armpits and around the back end.
4. Notice whether your dog is scratching, licking, chewing, rubbing or rolling more than usual, as this can point to irritation.
5. Check for any change in smell, oiliness or greasiness, which can sometimes go along with skin or coat issues.
6. Think about recent changes such as a new shampoo, more frequent washing, a new grooming routine, diet changes or more time outdoors.
7. Look for fleas, flea dirt or signs of other parasites, even if you haven’t seen the dog scratching constantly.
Common Causes
Seasonal undercoat shedding is the most common reason, especially when the weather changes or the coat is blowing out.
Dry skin, grooming neglect or a coat that has become packed with dead hair can also make the skin more visible.
Rubbing from collars, harnesses or repeated scratching can thin the coat in specific areas.
Less commonly, skin allergies, parasites, fungal issues or another skin condition may be involved, especially if there is itchiness, redness or patchy loss of fur.
What To Do
Brush your dog regularly to lift out loose undercoat, but be gentle if the skin underneath looks sore or sensitive.
Keep an eye on whether the shedding is improving over a week or two, or whether it’s spreading, becoming patchy or starting to look inflamed.
Avoid using human shampoos or over-washing, as that can sometimes make dry or irritated skin worse.
If your dog wears a collar or harness for long periods, check that it isn’t rubbing the same areas repeatedly.
If the coat looks dull, the skin seems uncomfortable, or the shedding doesn’t settle as expected, speak to your vet for advice.
Products That May Help
If your dog is shedding heavily, routine grooming and washing can help you keep on top of loose coat, skin debris and general hygiene as part of normal coat care.
