Hormonal Changes Hormones play a large role in your dog's emotional state, and when surgical procedures disrupt your pet's hormone levels, depression often follows. Dogs who've been spayed or neutered are the most likely to suffer hormonally triggered depression, thanks to the removal of their reproductive organs.
Generally, spaying or neutering your pet will not change its personality. If there are any effects on behaviour, they tend to be positive (reducing unwanted behaviour). Spaying or neutering will not change your pet's affection level or playfulness. For females, there is typically no change at all.
Could losing its genitals make your cat a little blue? Studies show if you remove a woman's ovaries for medical reasons, you increase her risk of anxiety and depression.
After Spay Surgery
Sometimes, a pet who is spayed can return home the same day. Other times, she may need to spend the night under veterinary supervision. Pain medication can be given to your pet if she needs it, but most don't. Your pet may be nauseous following the procedure and not want to eat for a day or two.
Neutering is a reasonably safe process; however, you can expect sharp changes in your dog's attitude right when you bring them home from the procedure. These side effects can range from increased aggression, depression, anxiety, or even clinginess; however, they only last for a short amount of time.
The pain medication used while your dog was in hospital, as well as pain medication sent home, can often cause signs of depression. Your dog is likely to be lethargic and less active during the recovery period.
An age of six to nine months of age may be appropriate for neutering or spaying a toy breed puppy or small breed puppy but a larger or giant breed may need to wait until they are near or over 12-18 months of age.
There are some old wives' tales that a dog should go through at least 1 heat cycle before she's spayed. This just isn't the case. Studies have shown that the risks of mammary cancer and urinary incontinence are higher if you wait to spay your dog after she's gone through 1 or more heat cycles.
To be clear, the question here is whether or not to spay early or after the first heat cycle. Because of significant risks of pyometra (uterine infection) or mammary cancer late in life we recommend that all female dogs not intended for breeding be spayed before their second heat cycle.
For these, it often takes two to three days for dogs to return to their normal selves after a spay and one to two for a neuter. Dogs over three years of age may take a day or two longer to recover. In many instances, older dogs (over six) can take up to a week to feel completely better after a spay or neuter surgery.
Will my pet become depressed or be upset with me? Getting your pet spayed or neutered will most likely not alter your pets basic personality. It can result in some behavioral changes, but usually for the better! Pets may be less aggressive, more relaxed, and more focused on you.
Myth: Spay or neuter surgery is painful and can harm my dog or cat. Truth: During a spay or neuter surgery, dogs and cats are fully anesthetized, so they feel no pain. Afterward, some animals may experience some discomfort. With pain management medication, pain may not be experienced at all.
The short answer is that no, your dog isn't likely to be less hyperactive after getting spayed or neutered. It won't change their personality much, if at all. Each dog has its own positive and negative social habits.
Spaying your dog reduces any aggressive behavior patterns so your dog will likely be less aggressive toward people and other dogs after spay surgery.
A University of Georgia study, based on the medical records of more than 70,000 animal patients, found that the life expectancy of neutered male dogs was 13.8% longer and that of spayed female dogs was 26.3% longer.
Spaying young females significantly increases the risk of osteosarcoma (bone cancer), a common cancer in larger breeds with a poor prognosis. #2: When female dogs are spayed before puberty, distinctly female disorders rise. The risk of recessed vulva, vaginal dermatitis, and vaginitis increases.
– Irritability
Each heat cycle brings significant hormonal changes in a dog. Some females become irritable or anxious and others might feel pain. Because spayed dogs don't have to go through these hormonal changes, their behavior may be more consistent.
Even if your dog is acting weird after being spayed, it's not necessarily a long-term change. Whining can occur when the dog is bored, sensitivity or urination is possible due to the surgery itself, as is irritability while the hormones are still balancing.
Desexing will not change your dog's personality. Male and female dogs that are desexed have a nicer temperament as they are not as driven by their hormones and make much nicer family pets.
Desexing has consistently been shown to change various health risks, including a reduction in pyometra and mammary tumor risk, as well as an increased risk of cranial cruciate ligament rupture, several forms of cancer, and obesity in both sexes. Other health effects vary considerably between breeds and sexes.
Our study of the stress-response system in spayed/neutered dogs leads us to believe spay/neuter adversely affects the dog's behavior and personality. In fact, the documented changes in the stress-response system would predict an increased level of fear and anxiety, which in some dogs can result in aggression.
