When we feel cold, dogs also feel cold but that are not same as human being. In general all animal has the power to adapt nature where they live. If you gave sweaters to dogs at the child, then you have to give sweaters to the dog right now else there is no need to give sweaters to a dog. There are so many companies now for dog sweaters and they are advertising about dog hooded sweatshirts to increase their marketing values but in actual there are no need use it. In actual pet clothing’s are now become a fashion today. But in original we are forcing pets or animal to loss their adapting power. If you have seen the movie about the “Spartan”, they were human being, but by using the nature how they created their body and strength. But in now days we can use a dog sweaters for new adaptation.
