Hi I have a 18 month old LAB who is moulting a lot at the moment just wondering if it is normal for a LAB to lose a lot of hair from the sides of his body.His hair is thin at the sides of his body but elseware is thick and looking healthy just wandered if this is normal for this time of year. I have noticed a lot of hair around the house. Also you can see a difference in colour in his skin where is hair loss is.
