DOG SUNSCREEN SKIN
As you can see here, SPF 30 provides human skin with 97% protection against UVB. I used to believe that a much higher SPF would give me much greater protection, but this isn’t true. SPF only tells you about protection against UVB – there is no system indicating how effective a sunscreen is for UVA protection. To make matters worse, the SPF system was developed before we knew how damaging UVA could be. Also, there are many other factors which can shorten the amount of time you are protected, for example, how intense the sun is, or if you go for a swim. Unfortunately, reality is not quite as simple as the theory! No sunscreen is effective after two hours, no matter what SPF it is. So, if it usually takes me 10 minutes to burn and I apply an SPF 30 sunscreen, I can theoretically stay in the sun for 300 minutes. SPF tells you how much longer a human can stay in the sun without burning than they could if they didn’t use that sunscreen. Unfortunately, it is a greatly misunderstood number, and the packaging of most sunscreens does little to help explain what it means.Īnd, as we’ll see shortly, it is even more complicated when it comes to dogs! Sun Protection Factor, or SPF, is the key selling point for sunscreens. Finding the right broad spectrum sunscreen is a great way to protect them from this. Skin cancer and its treatment in dogs can cost thousands of dollars and cause them untold distress.

When thinking about your dog, you need to protect them against both the short-term effects of sunburn as well as the long-term cancer risk. Over time this, too, can lead to skin cancer. It is UVB that causes the classic symptoms of sunburn, including redness, peeling, and blisters.

Ultraviolet B (UVB) damages the top layer of skin.Over time, the damage accumulates which leads to premature aging and can cause skin cancer. However, every time skin is exposed to UVA it damages the DNA. It doesn’t change the surface of the skin visibly beyond a slight reddening. Ultraviolet A radiation (UVA) penetrates deeply into the skin.You may sometimes see these sunscreens marketed as ‘UVA/UVB’ sunscreens. For this reason, it is vital to look for a sunscreen with broad spectrum protection.īroad spectrum means that a sunscreen will provide protection against both types of ultraviolet light which can harm your skin. The sun attacks human and dog skin in exactly the same way. To make sure your dog’s skin gets the sun protection it needs, and to ensure it is completely safe, there are several core features to look for: Broad spectrum protection
