Would I have to go through any math, physics, or chemistry courses to get a degree in animal behaviorism? I love psychology but I find it difficult to enjoy the three other courses I just mentioned.

For a degree, yes.

Here's a good link that may help.  The field broadly includes everything from dog grooming to employment in academic settings and research.
