dog : a highly variable domestic mammal (Canis familiaris) closely related to the gray wolf — Webster
Domestic dog (Canis lupus familiaris when considered a subspecies of the wolf or Canis familiaris when considered a distinct species) is a member of the genus Canis (canines), which forms part of the wolf-like canids, and is the most widely abundant terrestrial carnivore. The dog and the extant gray wolf are sister taxa as modern wolves are not closely related to the wolves that were first domesticated, which implies that the direct ancestor of the dog is extinct. The dog was the first species to be domesticated and has been selectively bred over millennia for various behaviors, sensory capabilities, and physical attributes. — Wikipedia

Imagine constantly living with mice. Every time you open a cupboard to get linen, clothes or food, mice have been or are still there.

If a friend boasts of having a "big-brained" dog, your reaction is probably not to ask "relative to what?" You would simply assume your friend thinks their dog is pretty smart. But are we always right to equate big brains with greater intelligence?

Robotic lawn mowers running at night have, by some, been declared a great threat to the population of European hedgehogs. Now a recently published study conducted by Dr. Sophie Lund Rasmussen, known as Dr. Hedgehog, and colleagues from Oxford University and Aalborg University sheds new light on the topic. The study shows that different models of robotic lawn mowers vary substantially in their capability to detect and avoid hurting hedgehogs. In fact, certain technical features significantly […]
- Blood transfusions in cats: A precious resource...on April 26, 2021 at 4:30 pm
Blood transfusions are a common procedure in medical practice in which donated blood is used to replace blood lost to injury or surgery or to treat serious medical conditions. The procedure is not performed as routinely in the treatment of pet cats—but, as in people, can be lifesaving. The availability of donors has been a limitation in primary care veterinary practice, but with the growth of blood banks providing greater access to feline blood, the procedure is likely to become more […]
