Many people ask about what is the best sex of a dog to get. This article is written by a breeder who breeds Boxers and Collies, but many breeders will agreed with the sentiments of this article irrespective of what breed a dog is.
Differences in behaviour
Most people see males dogs as more aggressive than their female counterparts, and that they can exhibit strong sexual behaviours, even when they are ‘fixed’. Typically females are more moody and emotional than males and can be harder to deal with at times. Females who are not neutered, will have regular heat cycles and these can be a handful to deal with. Like humans, female dogs will experience increased levels of hormones and can at times result in excessive shedding of your dogs coat. In tact females, when in heat, have the ability to destroy a house with their hairs !
Generally dogs will go into heat twice a year, and can last up to 3 weeks long. During these periods, females are more likely to start fights with other females and to will seek to entertain males.
On the other hand male dogs tend to be more affectionate than their female counter parts. They are not as independent and generally demand more attention and time. Males are more outgoing, more likely to interact with other dogs. Males
Cost difference between Male and Female dogs
As a rule of thumb male dogs are less expensive as females, and are generally easier to come by. The reason for the price difference is because of the breeding possibilities with females. Also breeders are more likely to buy more females than males.
Another point to consider is the cost of getting your dog neutered / spayed / fixed. For females the operation is more complicated and can cost up to two/three times as much as it would for males.
From my experience males make better all round pets.
