Shedding excessively can have many reasons: 1) change of seasons...your dog sheds his summer hair to get a winter coat (this will depend on your climate) 2) food quality is not adequate 3) ectoparasites such as mange mites, demodex mites, fleas, ticks, etc. itch and the dog scratches excessively and loses a lot of hair 4) some dogs naturally shed more than others. 5) hormonal changes, e.g. your dog comes into heat. Females will shed their hair coat You can do the following: 1) feed a good quality complete commercial puppy food for large dogs 2) Check for ectoparasites and treat for them if present 3) Brush or comb your dog every day This should minimize the shedding.

    Hi, thanks for using PetCoach! Due to her age she could be shedding her puppy coat. Shedding is normal and occurs based on the hair cycle. It can also be exacerbated by the season or weather. You can try an Omega 3 fish oil and frequent brushing to see if it helps. As long as she isn’t scratching excessively or has areas of hair loss it is likely normal.
