There is nothing like seeing a dog walking next to his human buddy, both of them wearing boots to protect their feet from the snow. While at first, this might seem a bit funny, when you stop to look at the big picture, it makes great sense. A good set of puppy booties will protect your pup's feet not only from the wet and freezing cold snow, but they will also protect his paws from the chemicals used to treat the roads and any sharp objects that might be buried in the snow.
However, keep in mind that there is nothing about wearing boots that comes naturally to your dog. It is likely to take a bit of time and effort getting him used to wearing them. Be sure to go to a pet store to buy your dog boots. Just like you, your pup needs the right size boots to fit his paws.
In this case, the idea behind the command is that when you tell your pup "time to put your boots on" he comes over to you and patiently allows you to put his boots on before you go for a walk. Once he finally gets used to wearing them, you may find he starts asking for them and no longer wanting to get his paws wet. Be sure you take the time to make the boot fitting process as much fun as possible as this will go a long way towards getting him used to wearing them.
The more time you spend getting your pup used to wearing his boots, the easier it will be teaching him how to walk around in them. Most forms of training start with letting your pup get used to a new item or situation.
The best place to start is at your local pet store that sells dog boots. Be sure you take your pup into the store with you and make a big fuss out of finding the right boots. At the same time, make sure the ones you choose fit him properly or he won't want to wear them. The only other things you need are:
One last thing, if your pup is already used to having his paws handled for things like nail trimming and fur trimming, you may find the training process goes a bit faster. Also, during the fitting process, just have your pup stand in the boots, do not let him try to walk around in them. Make it fun, make it a positive experience, and use plenty of treats and kind words.
