Yes, our guys are crate trained. They were crate trained by the breeder, so were already used to being in a crate before we brought them home. When they were puppies, we had a double crate that they shared, but as they got older, we realized how different their personalities were. Bulldozer is our very laid back lazy guy, ( that's why we call him Dozey) lol
He is happiest to sleep and cuddle, he doesn't like to walk, and will play for about 20 mins, and then be tired out and sleep for hours. Blossom has so much energy, she will walk for hours, and she is in play mode all the time. She will snuggle too, but it's on her terms, and mostly in the evening, and after she tuckered herself out with play. She wouldn't let Dozer sleep in the double crate, she would bite on his ears, jump on him and wanted to play, so we bought two separate crates, and they are side by side, but they have their own spaces. It's funny to watch them when they are sleeping because they always seem to sleep in the same position, same direction or same spot as each other. They sleep,in their crates at night, and are only in the crates during the day if we go out, and can't take them with us. We usually take them with us most places, but when we can't, it's safer for them to be crated as they eat and chew things.
