Yes, papillons do shed, but not excessively. It is a seasonal process, and it may happen in the spring, fall, or both.
In general, papillons shed in much smaller amounts than shedding breeds such as golden retrievers or labrador retrievers, but there are some factors that might affect this for your specific dog.
In colder weather, paps tend to shed less than in warm weather.
Some people have noticed an increase in their paps’ shedding as the weather becomes warmer, and some have even noticed a spring/fall bloom.
The latter has been noticed by owners who live in colder parts of the country where it stays cooler longer into the fall and even into winter, forcing the pap to maintain its coat during those months.
In either weather, you should notice a small decrease in the pap’s shedding as it starts to get colder or warmer outside.
In cold weather, the pap may shed lighter coats prior to going into its full-blown coat and again when transitioning out of its coat and into one that will be short or semi-longhaired for winter.
On the other hand, in warmer weather, you will notice an increase in shedding during the periods when the pap’s coat is preparing for molting.
Typically it will be spring that brings about this ‘bloom’ or stage of increased shedding where there are more hairs than usual on your clothes and furniture.
However, many times owners have also noticed an increase in shedding as the warmer months of summer approach.
Sometimes, you will not notice any trends in terms of weather and its effect on your pap’s shedding.
Depending upon the climate where you live or even what part of town inside larger city limits you reside, there are various factors that might affect these phenomena for your papillon.
If your pap is an indoor dog, you might not even notice a difference in the amount of hair it sheds as the weather changes.
As long as its diet and general health remain stable, or as stable as they can be with some conditions that are often at least somewhat hereditary, there would only really be one reason for concern if you were to notice an increase in shedding as the weather changes: allergies.
If your papillon happens to be one that is genetically predisposed to some sort of allergies, such as an allergy to pollen or some other allergen it comes into contact with on a regular basis (flies, perhaps), then you might see an increase in hair loss during those periods of the year when the allergens are abundant.
This is especially true if your dog spends most or all of its time indoors.
Some paps have general allergies that may not tie directly to a specific season, but rather just affect them throughout their lives.
These types of allergies occur in response to something that your dog inhales, ingests, or comes into direct contact with.
Usually, these allergies are diagnosed in paps when they are quite young because it is usually discovered that they have an adverse reaction to something in their food.
