One of the most important precautions is to keep the dog's nails trimmed. Long nails cause a dog to spread his or her toes when they walk.Nails that are too long can also have an effect on the dog’s weight distribution. Long nails cause the weight to be placed onto the back of the feet. Dogs can slip and injure themselves. :\
It is important to keep the hair between the dog’s pads trimmed. If the hair it not trimmed, it makes it easier for snow and ice to stick to the fur and build up into clumps or balls.Dog owners must perform routine daily foot pad checks, especially during the winter months. Ice and snow melt products made from rock salt can cause a dog’s pads to dry out and crack. These cracks provide an ideal environment for snow, ice and grit to accumulate. The accumulation of debris can cause sore feet, blistering and infections. A daily examination of the feet can help you find problems and treat them before they become serious.There are commercial products that can be applied to a dog’s pads to keep them supple. A light layer of Vaseline can be used to accomplish the same thing.It is a good idea to wash your dog’s feet after a nice walk on the street, or even the park.

Dogs that love to be outdoors in winter can benefit from a pair of good boots. Not only will the boots protect the food pad surfaces. Boots can help the dog retain its body heat and lessen the threat of hypothermia. Most dogs will require a “breaking in period” to get used to wearing boots. However, once they do get used to them, they’ll be glad to lift their feet so you can help them get ready for their romp outdoors.No matter what you do, dogs can still injure their foot pads and their nails :I but anyway

I really hope that I helped you.
