Well, you made it. A year ago, you brought home a tiny, chaotic bundle of fur who chewed your shoes, woke you up at 3 am, and somehow still managed to steal your heart completely. Now, here you are, the proud owner of an almost-grown-up Cockapoo!

Over the past 11 months, we've covered a lot of ground: teething, toilet training, parasites, nutrition, grooming, socialisation, and everything in between. This final blog in the series is all about what happens next. Because there's still plenty to think about as your Cockapoo transitions from puppyhood to an adult.

Here’s a simple, practical guide to what to expect and how to support your Cockapoo at this exciting age.

When does my puppy become an adult dog?

Small breeds mature much faster than larger breeds. Here, we use the term “adult” to mean physical maturity (being fully grown), though emotional maturity may take longer. As Cockapoos can range from small to medium size, depending on their Poodle heritage, their time to grow into adulthood can also vary.

• Small Cockapoos (i.e. from Toy to Miniature Poodle genes): around 12 months old

• Medium Cockapoos (i.e. from Miniature to Standard Poodle genes): 12–15 months old

When should I switch my Cockapoo from puppy to adult food?

When your Cockapoo reaches adulthood, it’s time to transition from puppy to adult food. Puppy food is specially formulated with higher calories and extra minerals to support growth. Once your dog is fully grown, these are no longer needed and could even contribute to weight gain.

It’s important to switch gradually, as sudden changes can upset your dog’s tummy:

• Days 1–3: 75% puppy food, 25% adult food

• Days 4–6: 50/50 mix

• Days 7–9: 25% puppy food, 75% adult food

• Day 10 onwards: 100% adult food

Vet tip: Keep a close eye on your Cockapoos weight and body condition during the transition and afterwards. You may need to adjust portion sizes slightly. 

As you have probably found out already, Cockapoos can be stubborn at times and believe they know what is best. They may prefer the calorie-dense puppy food and refuse adult food, but stick with it to transition fully for the best nutrition for your pet.

If you’re unsure when to start the switch or which adult food is best for your dog, our online vets are here to help.

Should I book a vet check-up for my Cockapoo?

This is a perfect time for a check-up with your vet, especially if your Cockapoo hasn’t been seen since their puppy vaccinations. Even if they seem healthy, regular vet visits are one of the most valuable ways to keep your dog well. Routine visits help your vet understand what’s normal for your dog, so that it’s easier to spot subtle changes down the line. Remember, dogs age much faster than we do. 

For Cockapoos, these routine check-ups are a great opportunity to monitor:

• Coat and skin condition - checking for early signs of allergies or irritation

• Ear health - floppy, hairy ears can be more prone to infections and wax build-up

• Nails and dental health - helping spot hidden issues before they become more serious

• Behaviour and well-being - a good chance to discuss training, anxiety, or any new habits or behavioural changes

Behaviour, training and life skills

Cockapoos continue developing mentally well into their second year, and without continued stimulation and reinforcement, behaviours can start to slip. A well-exercised brain is just as important as a well-exercised body! Boredom or frustration can lead to anxiety and destructive behaviour. 

Social maturity starts around this age. This means Cockapoos can push boundaries, and you might notice a regression in their behaviour and training. For example, being more distracted on walks, and not listening. Going back to basics with training can help. Practising basic commands such as sit, stay, watch me, and recall with high-value treats can help.

Keep their minds engaged:

• Continue gentle, positive exposure to new environments and people. You might notice your dog becomes more selective with who they want to be friends with.

• Consider a dog sport or activity suited to their energy level (such as agility or scent work).

• Keep regular training sessions going, and reinforce basic commands. Your dog's attention span should be better at this age, but they will also be more independent. 

• Continue using lick mats, puzzle toys and other mental enrichment games.

Exercise and sleep needs

At this age, most Cockapoos are ready for more exercise, but it’s important to be careful, as they can still be prone to injuries. Activities like swimming or gentle jogging are great ways to keep your dog fit and build muscle while maintaining a healthy body condition. But have a chat with your vet before tackling those mountain hikes or marathon runs to make sure your dog is ready.

Sleep is just as important at this stage. Most adult Cockapoos need around 12 to 14 hours of rest each day, though this can vary depending on how active they are. A well-rested dog is a much happier dog!

Insurance and microchipping

If you haven't already, make sure your dog is microchipped. This is a legal requirement in the UK and many other countries, and it’s a vital safety net if they ever go missing. Make sure that your contact details on the microchip database are up to date.

Now is also a good moment to review your pet insurance policy. Make sure you have the right level of cover, particularly for any breed-specific conditions your dog may be predisposed to. 

For Cockapoos, this includes:

• Ear infections

• Joint and hip issues

• Skin irritations and allergies

Your 12-Month Puppy Checklist

• Book an annual health check with your vet

• Don’t forget the parasite preventatives - especially fleas, ticks and worms

• Plan the puppy to adult food switch

• Discuss neutering if not done yet

• Continue daily tooth brushing

• Check paws, ears, eyes and skin daily for any abnormalities

• Keep up regular exercise and mental enrichment

• Make sure they are getting enough rest

A note from our vets to you

Getting a Cockapoo puppy through their first year is no small feat. You've navigated sleepless nights, chewed furniture, vet trips, vaccinations, training classes, and about a thousand questions about what is normal and what isn’t. You should feel genuinely proud.

The bond you build with your pup in this first year is the foundation for everything that comes after. Dogs who are well socialised, consistently trained, properly fed, and regularly seen by a vet live the happiest lives and bring the most joy to the families who love them.

Here's to many more years together.
