The shelter provided by the nest built in sows is of utmost importance to thermoregulation. For the first two weeks of the piglets life their physiological thermoregulation is still developing, and due to a lack of amount of brown fat tissue, piglets require an increased surrounding temperature. Without the protection of the nest, the piglets ...
The risk is 5–6% (similar to that of a woman in her early 40s giving birth), [393] [394] compared with a baseline risk of 3–4%. [394] The effects of inbreeding depression , while still relatively small compared to other factors (and thus difficult to control for in a scientific experiment), become more noticeable if isolated and maintained ...
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
Domestic cats, dogs, and primates, such as humans, are some of the best-known altricial organisms. [14] For example, newborn domestic cats cannot see, hear, maintain their own body temperature, or gag , and require external stimulation in order to defecate and urinate. [ 15 ]
Dogs are even more susceptible than humans to heat stroke in cars, as they cannot produce whole-body sweat to cool themselves. Leaving the dog at home with plenty of water on hot days is recommended instead, or, if a dog must be brought along, it can be tied up in the shade outside the destination and provided with a full water bowl.

In neonates (newborn infants), brown fat makes up about 5% of the body mass and is located on the back, along the upper half of the spine and toward the shoulders. It is of great importance to avoid hypothermia, as lethal cold is a major death risk for premature neonates. Numerous factors make infants more susceptible to cold than adults:
Pyometra is a result of hormonal and structural changes in the uterus lining. This can happen at any age, regardless of how many heat cycles have occurred or previous pregnancies (or lack thereof), although it becomes more common as the dog gets older. The main risk period for a female is for eight weeks after her peak standing heat has ended. [2]
