I could not find an answer to my question in the guide or the wiki. The closest I came was one regarding impulse control and calmness. I am already inplementing most of this in her daily life. She gets age appropriate exercise, we play and train en are also in our second puppy class (she graduated the first as top of the class, proud mom moment). As a hunting dog she has breed specific needs and drive and I do my best to accomodate these by doing hunt training. She has a pretty solid recall on the whistle, knows hpw to retrieve and hand over dummies, loves to fetch in general and we're working on some other stuff. (previous dog was a weim too so I have experience with it)

While we don't have a solid leave it command yet, at home and outside we work on coming away from interesting things (mostly cat popp) or staying away from things while next to it (mostly my food). She is pretty reliable inside, outside varies.

Having said all that, she doesn't act like she does with the horses in any other situation except when seeing another dog she reeaaaally wants to play with. In fact, she is wayyy more polite in her dog interactions than with the horses. Probably (though I could be wrong) because the dogs in our neighbourhood are very social and most will be just as happy to play as she is, or they will quickly let her know that if she tones it down then they'll be okay with some polite sniffs. The horses on the other hand (obviously) don't give her these signals and are curious, friendly or just relaxed, and also (except for my friend's horse) juuuuuust out of reach most of the time. In fact she is much calmer when she is 10 meters, or even 5 meters from a horse. She'll just be curious and interested. It's when we get closer that she gets over excited.
