Why is my 4-month-old Shih-tzu mix puppy shedding so much?

It sounds like Garry may be shedding due to seasonal changes which is perfectly normal. I find that the best way to combat seasonal shedding is daily brushing - you may want to look into using an undercoat brush if his coat is very thick. If he is shedding so much that you can see bare spots, if his skin seems irritated, or if his coat is dull I would recommend seeing your veterinarian to make sure he doesn't have a skin condition or parasites.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Lily Cruz! Is Lily scratching? I would have her seen by your Vet. The most common causes of excessive shedding and areas of balding are: demodex (non-contagious mite), ring worm and a skin infection. Demodex can be easily treated with one of the oral flea/tick preventatives (Nexgard, Simparica or Bravecto). Skin infections are treat with antibiotics or anti-fungals if it is yeast. Ring worm can be a bit more complicated. I do not think it is normal shedding because she shouldn't have areas that are thin or balding. I wish you the best!

It is possible that Tank is loosing some of his puppy coat now that he is 1 year old. Also I would make sure he does not have any signs of fleas or parasites that might cause an abnormal coat/ pet to lose hair. I would recommend an aloe and oatmeal shampoo. If that does not help I would recommend taking Tank to a vet to make sure nothing more is going on which might affect the coat growth. Hope that helps

I am sorry to hear about your puppy. Many different things can cause hair loss, also known as alopecia, in dogs. Parasites of the skin such as mange mites and fleas can cause this. Bacterial or yeast infections of the skin can also be a cause, as well as some genetic disorders. I would recommend an examination at a veterinarian to determine the cause of the hairloss which will help guide treatment recommendations, which may include medication to treat for mange, antibiotics or medicated shampoos.

Daisy could be shedding, which is common in the summer season when it's hotter. It can also be a sign of fleas, mites, allergies, or ringworm. It would be good to have her checked out by a vet to be safe to make sure that she isn't suffering from any of those conditions.

It is unlikely to be a genetic mutation. However, shedding can have medical causes such as mites, ringworm, auto-immune disease, stress, hormonal or nutritional causes. Sam is a bit old, but this could also be related to transition from puppy coat to adult coat. Just to be safe, I recommend seeing your vet. Best of luck to you and Sam!

Shedding large amounts of hair at one time in a puppy at any age between 4-8 months is going to be normal. There are estimates to when a pet should shed, but again you have to take into account that there is a bell curve with any estimate, so some dogs fall to the left or right of this. Dogs can also shed at multiple intervals, because the entire shedding process can be broken up into phases. You know you are dealing with an actual skin issue when you see patches of bald areas on the skin. As long as she doesn't have alopecia areas then this is considered to be a normal shedding process. Good luck with your new pup!
