Dormice are small rodents, with body lengths between 6 and 19 cm (2.4 and 7.5 in), and weight between 15 and 180 g (0.53 and 6.35 oz). [6] They are generally mouse-like in appearance, but with furred tails. They are largely arboreal, agile, and well adapted to climbing. Most species are nocturnal.
The same year, using camera traps and Spurentunnel (a tunnel-like device that forces animals to step into an ink container, and leave footprints), the first recorded sightings of garden dormice in more than 100 years were made in Büsserach.

Forest dormice produce a variety of noises for a variety of reasons. The most significant is the sound for an alarm call which is a melodious squeak. They also have the ability to produce ultrasounds which are used for communication. The different communication methods that forest dormice use are visual, tactile, acoustic, and chemical.

A study of dog remains indicates that these were selectively bred to be either as sled dogs or as hunting dogs, which implies that a sled dog standard and a hunting dog standard existed at that time. The optimal maximum size for a sled dog is 20–25 kg based on thermo-regulation, and the ancient sled dogs were between 16 and 25 kg.
Some owners do this routinely if they have a dog susceptible to ear infections or if they have a breed with heavy, floppy ears, which can hide early signs of inflammation. Dogs, like all Carnivorans, also possess two anal sacs, or scent glands. These sacs communicate with the surface of the skin by ducts which open on either side of the anus.
Dog intelligence or dog cognition is the process in dogs of acquiring information and conceptual skills, and storing them in memory, retrieving, combining and comparing them, and using them in new situations. [1] Studies have shown that dogs display many behaviors associated with intelligence. They have advanced memory skills, and are able to ...
