Desexing female dogs - the advantages

1) Prevent unwanted litters of puppies

Recent publicity has highlighted the problems faced by the RSPCA and Animal Welfare Associations who have to destroy thousands of unwanted dogs each year.

For every pup that finds a good home, there is one less home for a puppy somewhere else. Unless you intend to breed on a professional basis (which involves a lot of hard work, time, and money) it is better to have a female dog desexed.

2) Prevent "heat" periods

A female dog in season will attract male dogs from afar - many of whom are quite athletic when it comes to jumping high fences.

3) Reduce the risk of mammary cancer

Desexing before a dog's 1st season will substantially reduce the risk of her developing malignant mammary cancer at a later stage in life (up to 99% protection). This protection rate drops off quickly after 2-3 seasons.

4) Prevent womb infections (pyometra)

A large number of entire older female dogs develop a womb infection after being in season. This is a very serious and life threatening situation requiring an emergency hysterectomy and intensive care.

5) Prevent wandering

Desexed female dogs tend to stay at home more so than entire ones who often have an encounter with a motor vehicle. Desexing results in a more " homely " pet.

Disadvantages of desexing female dogs

There are not many disadvantages to desexing, and they are far out weighed by the advantages.

1) Weigh gain

Desexed dogs tend to put weight on more easily when fed the same amounts of food. As long as owners exercise their dogs regularly and keep control on amounts fed, this does not become a problem.

2) Urinary incontinence

Sometimes, older desexed female dogs start leaking urine when resting. This is easily fixed by using a new product, Propalin, which tightens up the bladder. Its is given as drops in the food and has a 90-95% success rate.
