Large mammals develop at an absolute slower rate compared to small mammals. Thus, the large mammal tend have longer gestation periods than small mammal as they tend to produce larger neonate. [18] Large mammals require a longer period of time to attain any proportion of adult mass compared to small mammals. [19]
The study concluded that while Australian Cattle Dogs are a healthy breed and do live on average almost a year longer than most dogs of other breeds in the same weight class, record ages such as Bluey's or Chilla's should be regarded as uncharacteristic exceptions rather than as indicators of common exceptional longevity for the entire breed.

The female Australian Cattle Dog measures approximately 43–48 centimetres (17–19 in) at the withers, and the male measures about 46–51 centimetres (18–20 in) at the withers. The dog should be longer than tall, that is, the length of the body from breast bone to buttocks is greater than the height at the withers, in a ratio of 10 to 9. [6]
Below you'll find large breeds and small breeds that make excellent livestock dogs/farm dogs. Some, like the German shepherd, can also guard your home and family, while others, including the Jack ...
The duration of this period varies between species. For most species, the amount a fetus grows before birth determines the length of the gestation period. Smaller species normally have a shorter gestation period than larger animals. [2] For example, a cat's gestation normally takes 58–65 days while an elephant's takes nearly 2 years (21 ...
She says, "The average lifespan for a small breed dog would be around 13 to 16 years, although many live longer. On the other hand, giant breeds may live around 7 to 10 years, and medium and large ...
A blue Australian Cattle Dog (Bluey's breed) Bluey's age, along with that of "Chilla", a Labrador Retriever and Australian Cattle Dog mix reported to have lived to the age of 32 years and 12 days (but not certified by Guinness), [8] prompted a study of the longevity of the Australian Cattle Dog to examine if the breed might have exceptional longevity.
Female dogs bleed during estrus, which usually lasts from 7–13 days, depending on the size and maturity of the dog. Ovulation occurs 24–48 hours after the luteinizing hormone peak, which occurs around the fourth day of estrus; therefore, this is the best time to begin breeding.
