What a great question to be thinking about — getting ahead of this decision is really good pet ownership!

The "right" age to spay a dog has actually shifted a bit in recent years, and for a Bernedoodle specifically, there are a few things worth knowing.

The traditional guideline was to spay around 6 months of age, before the first heat cycle. That's still common practice and works well for many dogs.

The newer thinking — especially for medium-to-large breeds — is that waiting a bit longer may have some benefits. Reproductive hormones play a role in bone and joint development, and some research suggests that letting those hormones do their job a little longer could support healthier joints long-term. Since Bernedoodles tend to be on the larger side (depending on the poodle parent's size), this is worth a conversation.

At 8 months old, Femke may already have had, or be approaching, her first heat cycle. That's completely normal and doesn't mean you've missed a window — it just becomes one more factor to discuss with your vet.

A few things your vet will likely consider:
- Femke's current size and expected adult weight
- Whether she's had a heat cycle yet
- Your lifestyle (for example, whether she's around intact male dogs)
- Any breed-specific health patterns your vet is aware of

There's no single universal answer here — it genuinely depends on the individual dog. Your vet knows Femke and can weigh all of these factors together to give you a personalized recommendation.


When to see your vet: This is a great topic to bring up at Femke's next routine visit, or you can call to schedule a dedicated conversation about it. There's no emergency here, but since she's 8 months old and the timing is relevant now, sooner is better than later. If she's already had a heat cycle or you've noticed any unusual discharge or swelling around her vulva, mention that specifically when you call.
