While Cavapoos’ size can be influenced by several factors, you can make educated predictions based on the breed’s standard size range and growth patterns.

Cavapoos typically reach full height by one year and continue gaining weight until about 18 months.

To predict your Cavapoo’s size, consider the size of its parents and grandparents. If they’re on the smaller side, your puppy will likely be smaller too. You can also track your puppy’s growth using a Cavapoo size chart.

If it’s consistently above or below the average for its age, you can expect it to be larger or smaller than average when fully grown.
