Very weird-looking synthetic dog for surgical training

I’d be interested in seeing what they do for the tissue portion. I imagine it would not be so easy to replace over and over on a synthetic model and that they probably do still practice on real tissue.

My assumption was this type of model would cut down on the number of animals that are used in medical training. (I’m old enough we did dissections in high school, and was with a program where I was able to get some hands on experience with human cadavers when I was 12.)
