Dogs sleep more than us, but they wake more frequently than we do. How much and when they sleep depends on the level of activity in their environment. A dog living as a pet in the home is likely to sleep more than a dog that works for a living, like a search and rescue dog or a dog working on a farm.
In the colder winter months, some rattlesnake species enter a period of brumation, which is dormancy similar to hibernation. They often gather together for brumation in large numbers (sometimes over 1,000 snakes), huddling together inside underground rattlesnake dens or hibernacula.
Garter snakes (genus Thamnophis), a very adaptable group of snakes, inhabit backyards and multiple grass habitats throughout North America. Their propensity to inhabit residential areas explains the common name, garden snake, the snakes recognized for their thin and often colorfully striped bodies.
