While everyone loves puppies, it is vital to avoid unplanned litters by preventing an unspayed bitch from coming into season unless you have responsible breeding plans. The heat cycle triggers strong breeding urges, causing bitches to seek mates, sometimes escaping supervision and resulting in accidental pregnancies leading to thousands of unwanted puppies born in the UK annually.
A female dog experiences her first heat or oestrus cycle from about six months old; larger breeds may start later, even up to 18 months. This marks puberty and fertility. Unspayed bitches usually come into season once or twice a year, with each cycle lasting up to three weeks. During this period, they can conceive, accompanied by hormonal and behavioural changes.
Finding puppies and understanding breeding begins with responsible choices. Spaying, a surgical procedure called an ovariohysterectomy, involves removal of the ovaries and uterus and is the most definitive way to prevent heat permanently. It halts the hormonal cycle, stopping heat and any chance of pregnancy.
This surgery also provides long-term health advantages including a significant reduction in ovarian, uterine cancers, and mammary tumour risks, as well as preventing uterine infections such as pyometra. Though it requires general anaesthesia and carries typical surgical risks, it remains the safest and most effective method advised by vets.
For some owners, spaying may not be immediately possible due to medical reasons or plans for future breeding. In these cases, hormonal contraceptives provide an alternative to prevent or delay heat cycles temporarily.
These include long-acting injections such as Delvosteron or Proligesterone that suppress the release of eggs or prevent implantation by manipulating the dog’s hormonal environment. The treatment protocol often starts with an initial injection followed by repeat doses over several months to maintain suppression.
However, these methods have drawbacks. They require strict ongoing veterinary management, carry possible side effects like weight gain, increased risk of uterine infections, and negate many benefits of spaying including cancer risk reductions. Additionally, fertility may not return immediately once injections cease, particularly after prolonged use over a year.
If hormonal contraception or spaying is not an option, managing a bitch’s heat cycles demands extra care. Close supervision to prevent contact with unneutered males is crucial to avoid unwanted pregnancies. Providing adequate enrichment can help reduce stress and behavioural changes common during heat, such as increased roaming or restlessness.
Using confined, secure areas outdoors and avoiding letting the dog off lead during this time reduces risk. Many owners seek boarding facilities known for heat-season care to prevent accidental mating during strong seasonal impulses.
Preventing your unspayed female dog from coming into season is primarily achieved through surgical spaying, which offers permanent cessation of heat cycles and significant health benefits. While hormonal contraceptives exist as temporary alternatives, they carry some risks and require ongoing management.
Responsible pet ownership means carefully considering the health and welfare implications of all options. Working with a vet and planning adequately assures the best outcomes for your beloved dog’s health and your household’s harmony.
