Lately my horse have been very sassy and not responding to my leg ? My horse has been grumpy and refusing to do want I tell him to do , any tips ?

It sounds like he might be sore somewhere
Since it’s all the sudden it’s probably pain or soreness related. A chiropractor or vet maybe be nessesary if the behavior continues or worsens.
