I have a friesian and she is perfect. Her temperament is absolutely lovely! She is only just rising 2 so i havent ridden her yet, but she has had a saddle on (once, briefly cos she pestered lol) and she is walked out in hand on the roads twice daily. I can honestly say that she has not put a foot wrong in the time i've had her. She is just perfect. Nothing seems to spook her. If there is anything she is at all unsure of she just stops and looks at it lol But she will follow me up to it and have a sniff, then carry on. She doesn’t do any of the spinning and spooking that other youngsters can do, she really hasn’t got a nasty bone in her body, she’s lovely.
I think you do need to look at the breeding of the horse you are buying also. Im not an expert on bloodlines at all, but like with most breeds, there are certain ones that will produce “hot” friesian. I think one stallion in particular (Tserk or something??) has been producing some with a more hot temperament than maybe you would like if you’re a novice rider or just not sure about such a big horse. My girl is by Brandus and from a mare by Jakob, both of which are apparently known for producing very placid, even tempered foals.
As for the bouncy stride… Check out some of my videos on Youtube. I cant give the link cos im at work and they block it lol! But if you stick “una, friesian” in the search you should come up with some of my (many!!) videos of her. Obviously she’s not yet been ridden but she has incredibly smooth paces. She lifts her knees high, but her back stays pretty level.
I would suggest you ride a few friesians before you consider buying on though. I was advised the same. The stride is very different to a lot of other horses and it can feel weird at first lol But once I’d got used to it I found it so comfy!! I cant wait to ride my Una now!!
Anyway. Hope that helped a bit. There are a few other friesian owners and breeders on here so you should get plenty of advice.
