Dogs shown in the conformation ring are not allowed to be either neutered or spayed. It disqualifies them from being shown as they must be intact and unaltered.

Dogs reach puberty between 6 and 24 months old, at which age female dogs will start having an estrous cycle. There are four stages of estrous: proestrus, estrus, diestrus, and anestrus. A dog in estrus, also known as being "in heat", can become pregnant during this 3- to 21-day period. [3]
A female dog is usually diestrous (goes into heat typically twice per year), although some breeds typically have one or three cycles per year. The proestrus is relatively long at 5 to 9 days, while the estrus may last 4 to 13 days, with a diestrus of 60 days followed by about 90 to 150 days of anestrus.

These dogs can withstand high heat without tiring and need—or rather, love—tons of exercise. In fact, an Australian kelpie named Abbie is the top surfing dog in the world because that is a ...
Female dogs have their first estrus ("heat") at 6 to 12 months-of-age; smaller dogs tend to come into heat earlier whereas larger dogs take longer to mature. Female dogs have an estrous cycle that is nonseasonal and monestrus, i.e. there is only one estrus per estrous cycle.
