How can I trap dog hair in my washing machine?

[MsVestibule]

We have a dog who casts a lot. The washing comes out the washing machine still covered in his hair! I know there are products which you can throw in the washing machine that attracts the hair, but has anybody tried one that works well?

This is meant to be very good: Vamoosh - Pet Hair Dissolver for Washing Machines - 4 x 100g www.amazon.co.uk/dp/B076WZ1NG8/ref=cm_sw_r_cp_api_i_ZB2vEbKNP349M?tag=mumsnetforu03-21

A cheaper alternative is to put in a piece of fleece. Cat hair and human hair seems to weave itself into it. I think you can get the pet hair dissolver in £ shops, B&M or Wilko.

I bought a colour catcher not to catch pet hairs but it just seemed to be a flannel with a funny edging.
