Picking out a brand new puppy is always a joy.
But some of the most popular breeds are prone to hip dysplasia, badly formed hips that can lead to pain as the dog gets older.
There's a test, designed to spot problems as early as 16 weeks of age.
A doctor developed the PennHIP test.
It's designed to give owners a measure of hip laxity in their animals.
The looser the hips, the more prone to hip dysplasia.
