Do they do exams? I have a sick Dog she's a female and I need to get her to a animal clinic but don't have a lot of money I'm low income?

I found a coupon at pet smart website for a free exam. We were told they only do fixes and if they find anything during the spay or neuter

They did when i took my dog call them they are really friendly and i had a million questions when i went and they never got irritated with me
