Oestrogen, a vital hormone in female dogs, plays a key role in regulating reproductive cycles, growth, and even emotional balance. Removing oestrogen—whether through spaying, hormonal suppression, or health conditions such as ovarian disorders—can have significant impacts on a dog’s physical and emotional well-being.
Physical Effects
- Changes in Metabolism and Weight Gain
- Oestrogen helps regulate metabolism. After its removal, many dogs experience a slower metabolic rate, leading to weight gain if their diet and activity levels are not adjusted. This weight gain can increase the risk of joint issues, diabetes, and other metabolic disorders.
- Coat and Skin Changes
- Oestrogen influences skin health and coat condition. Dogs may develop a thinner coat, increased shedding, or a “puppy coat” texture. Skin may become more prone to dryness or infections due to reduced hormonal support.
- Urinary Incontinence
- In some dogs, the removal of oestrogen can weaken the urinary sphincter, resulting in urinary incontinence. This condition is especially common in spayed females and can be managed with medication or supplements.
- Bone Health
- Oestrogen contributes to bone density and strength. Its absence may predispose dogs to weaker bones and, in rare cases, an increased risk of fractures or osteoarthritis.
- Increased Risk of Urinary Tract Infections (UTIs)
- With lower oestrogen levels, the vaginal tissue and urinary tract may experience reduced elasticity and lubrication, increasing susceptibility to infections.
Emotional and Behavioral Effects
- Increased Anxiety
- Oestrogen has a calming effect on the brain, so its absence can heighten anxiety in some dogs. They may exhibit signs of nervousness, clinginess, or fear-based behaviours.
- Aggression or Irritability
- Hormonal shifts can make some dogs more prone to irritability or reactivity. This is not universal but can occur in dogs already predisposed to such behaviours.
- Lack of Motivation
- Changes in energy levels or shifts in hormone-related neurotransmitters can reduce a dog’s drive for play or training activities. This may manifest as lethargy or a general lack of enthusiasm.
- Compensatory Behaviors
- Some dogs, particularly those who rely on hormonal cues for social interaction or confidence, may exhibit compensatory behaviours like excessive barking, mounting, or mouthing.
How to Support a Dog After Oestrogen Removal
- Diet and Exercise Management
- Adjust the dog’s diet to match their reduced metabolic rate. Focus on high-quality proteins and controlled calorie intake. Pair this with regular, low-impact exercise to maintain muscle tone and a healthy weight.
- Behavioural Support
- For dogs showing increased anxiety or behavioural changes, focus on positive reinforcement training and calm-inducing routines. Consider enrichment activities to boost their emotional health and confidence.
- Supplements and Medications
- Supplements such as omega-3 fatty acids, joint support chews, or hormone replacement therapies (where medically advised) can address specific issues like coat health, joint strength, or urinary incontinence.
- Veterinary Check-Ups
- Regular veterinary visits can help monitor physical changes like weight, urinary health, and coat condition. Early intervention is key to managing any side effects effectively.
- Environmental Adjustments
- Creating a stable, low-stress home environment can support emotional stability, especially for dogs prone to anxiety or fear-based behaviours.
