Susan Goodlad

Puppy Food

  • From: Edinburgh, City Of, Midlothian, United Kingdom

How long should a pup stay on puppy food before progressing to adult food?

  • VioVet Staff

It is recommended to switch onto an adult diet when your dog is fully grown, at around 12 to 24 months dependant on the breed. In general the larger the breed the longer it takes to reach adult maturity.

The difference between puppy food


How can I tell if my puppy needs large robust puppy food or large athletic puppy food, she is a standard Labradoodle

  • VioVet Staff

Either diet would be suitable and safe for your Labradoodle. The Athletic diet is more aimed at energetic slimline dogs, like Weimeraners. Whilst the Robust diet is for bulkier dogs, like St Bernards. The choice will depend on your Labradoodle's physique.

Is a labrador considered a medium or large breed dog for Purina puppy food.


I have been feeding my 4 month old lab the Purina med dry puppy food and wondered if I should change to the large puppy variety?

  • VioVet Staff

A labrador would class as a large breed dog so I advise feeding the large breed puppy version of the Purina range.
