Is catching a called strike too much to ask?

[Bulldog]

(H.S. level and above)
A strike is a strike, I get it and I have heard the argument from both sides but, I still find it hard to call a strike if the catcher can't hold on to the pitch. For some reason, I feel this is happening in my games more this year than prior years. I'm starting to second guess myself and wonder if I should just start calling the strike even though the catcher drops the ball. I would love to hear from other on how they deal with this issue.
