Hair Particles collision with emitter going wrong

hi there!

i know there is tons on this, but i just can not seem to figure out why my hair dynamics are FREAKING OUT when i enable collider on my mesh.

i just want the hair on my sweet old cat and dog to behave natural and bounce and interact with the mesh normally when using dynamics and not going through the mesh all over the place, but it just does not seem to work!

anyone care to check? my file: https://www.dropbox.com/s/wto3kkij1qrqbaq/doggigltfwcat.blend?dl=0

would be much much appreciated im going crazy and can not find the answer.
