In the older days when dogs were living outside and chemicals were harsh (I remember my granny using dish wash liquid on her dogs!), there was most certainly a need to wash dogs less often.
Living in close proximity
In today’s modern society where we have less and less space and where we are more urbanised there may not necessarily be enough space to keep our dogs outside even if we wanted to. Some people live in small apartments and the only space they have are balconies. As generations developed, our animals became more and more our companions and our friends rather than animals whose place is outside. Our dogs share our chairs, sofas and beds with us. For this reason then, in the interest of hygiene it is advised not to wash your dog only once or twice a year. If left for such a long period of time, a lot of sweat and dander will build up. Your dog will be really smelly and it will all rub off on your furniture, bed and clothing. Parasites may go unnoticed and untreated and a lot of bacteria will be carried and rubbed off in your home.
pH of chemicals
In years gone by, chemicals were not as pet friendly as they are today. Pet shampoo manufacturers have in recent years however, invested a lot of money to pay scientists to investigate the appropriate pH level of shampoos and conditioners to make it optimum for doggy skins. These days a wide variety of shampoos are available, including “frequent wash” varieties which have ingredients such as aloe vera. In the older days there was a valid argument for only washing your dog once a year because of the harshness of the chemicals it ruined the natural oils of the dog’s skin and dried it out and caused skin conditions. But in today’s age, you need not have any fears. If you buy a good quality shampoo from a reputable company your dog’s hair and skin will be in safe hands
So how often then?
I would recommend washing your dog whenever he or she is dirty, but no more than once a week. If you happen to be out and your mucky puppy gets into the mud, just lift him or her into a basin of water and rinse their paws and undercarriage if they have already been shampooed this week. Washing every day or every other day will indeed dry out the skin, no matter what good shampoo you are using. If your dog is still clean and fresh smelling, there is no need to wash them.
