Hair loss in puppies can be caused by something as simple as heavy shedding, or by something more serious such as skin problems, parasites and more.
If you're worried about how much (or perhaps how little) hair your puppy has, or notice above-average shedding, bald patches, rashes or irritated skin, then it's important to find out what's causing the problem.. so that you can fix it!
Here's a look at the most likely culprits.....
Allergies are actually more common than most dog owners realize. They can develop allergic reactions to an ingredient (or several ingredients) in their food or treats.
Quite often this is to a food that has been eaten, and well-tolerated, for some time, but it can also develop after your pup has been given something new or different.
Other common 'triggers' for canine allergy symptoms are fleas, seasonal allergens (such as pollen, weeds, dust etc.).
Some dogs also have 'contact allergies' which means they react to something they come in contact with. This could be a shampoo, topical medication, cleaning product, material or fiber and so on.
Regardless of what causes the allergy, the reaction is usually seen as a skin problem.
Canine hair loss, or bald spots are common, as are excessive licking or scratching (particularly of the belly, legs, tail or face), red irritated 'hot-spots' or a rash.

Most puppies lose their puppy coat when they're somewhere around 3 - 10 months old, depending on size, breed and coat type.
This sort of puppy hair loss can be more extreme in some breeds than others, Pomeranians are a prime example of this, and may look very 'patchy' for a time.
Adult dogs shed seasonally, usually twice a year at the major change of seasons.
This is often called 'blowing coat' and dog hair loss can be pretty dramatic at this time. Regular brushing and grooming is essential when this happens, to prevent tangles, mats and so on.
A female dog will also shed during her heat cycles, and more heavily after having puppies.
Excessive dog hair loss can also sometimes occur during times of extreme stress such as illness, a reaction to surgery, or other anxiety-inducing circumstances.
Bathing your puppy too often, or with the wrong kind of products, can also cause thinning hair and dry, flaky skin.
There are several natural products and remedies that are gentle and soothing on your pups' skin, check out my Natural Health Products and Natural Remedies pages to see some of the best ones on the market.
There are quite a few illnesses or health conditions that can cause
puppy hair loss. Some of them may be congenital, some may be contagious
or a result of parasitic infestation.
There are too many to list definitively here, but a few of the more common medical reasons for a dogs' hair loss include:
Some breeds such Shar-Peis and Bull Terrier breeds seem to be particularly liable to develop demodectic mange, especially if their immune system is stressed.
With Sarcoptic mange a pup or dog will be extremely itchy and uncomfortable, and a dogs' hair loss can be fairly extensive as he may scratch himself very aggressively.
A skin scraping taken by your vet can determine which mite is causing the trouble.
