Phantom pregnancy (also called false pregnancy or pseudopregnancy) is a condition where female dogs feel pregnant, even when they are not. It can happen in any unspayed female dog, and signs usually start a couple of months after a season.
Dogs experiencing a false pregnancy will show signs of being pregnant:
- Nesting
- Carrying toys or other object as if they were puppies
- Mammary development
- Lactation (producing milk)
- Reduced appetite
- Lethargy
- Behaviour changes such as nervousness or aggression
Dogs are prone to phantom pregnancies because their normal reproductive cycle produces pregnancy hormones after every season whether they have been mated or not.
In most dogs symptoms are mild and will resolve on their own in a few weeks as the hormones subside. However, in some cases the symptoms can be severe or persistent and require medication.
Dogs prone to false pregnancy are likely to experience symptoms after every season, so spaying is always recommended in these dogs.
If you think your dog may be experiencing a phantom pregnancy then speak to your vet. They can examine her, rule out other conditions (including actual pregnancy!), and help you decide the best course of action.
Managing Phantom Pregnancy
Wait it out
Most cases of phantom pregnancy are mild and will resolve on their own within a few weeks.
Many owners do not even notice the signs.
You can help your dog’s symptoms resolve faster by discouraging any nesting or mothering behaviour:
- remove toys or blankets
- prevent her from licking swollen nipples
- make sure she gets lots of exercise.
Spaying
Dogs prone to phantom pregnancy are likely to show signs after every season, so spaying is the best prevention. Neutering also prevents life-threatening womb infections, mismating, and reduces the risk of cancer. The best time to spay your dog is 3-4 months after the end of a season, and if your dog is experiencing a phantom pregnancy you will need to wait until the symptoms have resolved.
Medication
In severe or prolonged phantom pregnancies your vet may recommend a drug called Galastop (cabergoline).
This is a medication that stops milk production and mammary swelling. It is given once a day for 5-7 days. Galastop may not be appropriate for all dogs so speak to your vet to see if it may be suitable for your dog.
