Compare and Contrast Dogs

I got three dogs. They are our family's pets. Their names are Happy, Dogu, and Wofu. Some of you may think their names sound strange and funny, and I agree. Two of my dogs are female, and the one been excluded name Wofu is male. All three dogs are very different even though they live together more than a year already. Two of dogs have the most differences, and minium list of similarties. They are Dogu and Wofu. First, Dogu is much cuter than Wofu. All of our family's dogs were street dogs before. We adopted Happy first, and after about 2 months, we adopted Wofu and Dogu. They were only about a month old when we adopted them. The first time when we family saw Wofu, we thought "Oh My God! Why is this dog so ugly?'', and then we saw Dogu, and then we thought "Oh My God! This dog is super cute!" At first, we were only going to bring Dogu back home, but we have sympathy on Wofu, so we brought him back.
Other differences are Dogu is much smarter than Wofu, and Wofu eat much faster than Dogu. We spent about a couple months to teach Dogu how to sit, but we spent over a year to teach Wofu how to sit! Even though Wofu is dumb, there is one thing he is super good at, eat! He eats a lot and eats them with super high speed. He eats so fast that he can finsh a plate of bones within 15 seconds! That is also why he throw out a lot, cause he eat too much. Other differences that I won't explain it very detail are: Dogu runs faster, Wofu is way heavier, Wofu barks more, and Dogu sleeps more. They have a few similarties, such as they both like to play and they like delicious food.
