I didn't list out every CE I ever attended, but I did put anything that was major and relevant. For example, I did a fairly involved CE with one of the vets I worked with under a teacher from Texas A & M that I included under vet experience. I know that's pretty vague, but I just looked at each course individually and made a judgement call as to whether they needed to be listed out. I only had the one that I listed separately - I've only been an RVT for a couple of years.
I also mentioned in my personal statement that I'd gotten my RVT license and had stayed up to date on CE. (I needed to mention it because the law is a little different here in MD - you can get it if you have a bachelor's, so I hadn't gone through a formal tech program.)
I put my specialization programs on there (ie Veterinary Dental Technician) but I didnt put all the CE Ive attended. Mostly, bc for me it would have been too much but I dont think its a bad idea. I guess it depends on how you interpret veterinary supervised experience. I would definately put any wetlabs you took.
