Getting balls to ball

I am a professional photographer but I am new to photographing bp's. Ive tried a few times but my bp doesn't want to ball up, she would rather stretch out lol. How do you get them to ball up with out scaring the crap out of them and stressing them out. I don't want to upset my poor girl just to get a photo.

try getting her on a cold day (when shes cold), she might be more willing to stay curled up, like maybe first thing in the morning (assuming you lower temps at night). other than that idk, cause if they dont want to curl up, they wont lol

Ive heard of people putting a bowl over them so they are in the shape of a ball? Then take the pic right after the bowl is moved? IDK. Good luck.

no clue i'de say its all personality my little boy always balls up but my girl refuses and wants to run all over you. good luck

I will try the bowl trick, thank you!
