Lunging, spending time grooming
I suggest liberty if you don't know what it is look it up on YouTube and there should be vi
what i did when i first bought my horse was i would just put her in the arena and free lunge her then when she was more calm i would just hangout with her in the arena for a little bit and get her to follow me around and trot beside me
Lots of grooming and getting to know each other on the ground.
Free lung him and have him follow u and girl, just pet him and love him and he will become a part of ur life so just wait n see 💜
free lunging and playing ground games there are a ton of vids on youtube about bonding games and stuff
Join up really builds a bond and also states where you and your new horse is in the pecking order. Best to show you are the leader from the start and they will feel more comfortable knowing their place in the 'herd' or partnership. Loys of grooming also helps too :)
Try lunging, and lots of love and treats :)
