The number of hours a dog is exposed to sunlight in a day (photoperiod) triggers the shedding process.
It is more noticeable in outdoor dogs in the spring and fall. Indoor dogs shed more consistently but in lesser amounts because of the artificial light inside the house.
What can you do about shedding? Providing your dog is just a normal shedding dog, here are some tips:
1. The first thing you can do to reduce the amount of hair in your home is to brush or comb your dog on a daily basis. This will help more than anything to reduce shedding. You are basically controlling the shedding.
2. Feed your dog a good quality dog food. Don't skimp. Stick with one of the premium brands.
3. Make sure your dog gets plenty of exercise. Healthy bodies promote a healthy haircoat.
4. Don't let your dog get fat. Keep your dog at an ideal weight. Obese dogs have difficulty grooming.
Dogs shed. Nothing will change that. But regular grooming will make the biggest difference.
