One of the Golden’s best assets is its golden coat. The best way to get a good coat is to grow it from the inside, and that means proper nutrition. You can help that coat stay healthy on the outside by brushing and washing.
Brushing a dry coat can result in hair breakage so mist it ever so slightly with water before you start. Your Golden Retriever should be brushed at least one to three times a week.
Never shave your Golden Retriever. You can use any pair of scissors to trim straggling hairs, but the main rule when trimming a Golden is that less is best.
It is normal for a Golden Retriever to shed their hair. If there seems a lot putting 1 teaspoon of olive oil in you dogs food per day may help reduce shedding a little. If you do find your Golden is shedding a lot then try to brush them every now and then and remove the extra hair before it gets on your furniture! If your Golden is not scared of the vacumn you can even vacumn your dog! Many dogs love to be vacumned (use a soft brush attachment).
It is usual to have some shedding with goldens all year round (in addition to replacing seasonal coats), but if it is excessive there may be some other underlying cause such as nutritional, stress or some other kind of imbalance so it would probably be best to double check with your vet if you are worried about excessive shedding.
