And my son asks me, "Why is Gufy (the dog) living in a house, with his wife and son, riding a car, walking in clothes and talking, and Pluto (also a dog) in the same series lives in a cone, walks on four legs without clothes and does not talk? This is what, different breeds of dogs7 What to answer?

= = = = = is = is = is = is = is = is = is = is = is

And we smoothly move to the color differentiation of pants ;-)
