Hello, I am not new to horses but am by no means an expert.  It has been about 8 years since I was around horses all the time.  Back in May I was finally able to get two horses of my own, Pipe and Taylor, who are both quarter horses.  They lady that sold them to me had Pipe for about 5 years and Taylor for about 2 so they had been together quite some time when I got them.  She had 15 horses so I guess she never had to deal with the seperation anxiety issues, this is also new to me since I have always been around large groups of horses (worked on a horse farm). 

These two are completely attached at the hip, they will not leave eachother for anything.  I have been spending most of my training time with Taylor who is the more independent of the two.  He will ride successfully for short periods of time, until Pipe begins screaming for him.  Pipe scares me that he will injur himself when I take Taylor away from him.  I can ride Pipe fine if Taylor is in the pasture with us, but I cannot stall Taylor and ride Pipe, he will buck the entire time. I have tried tying Pipe up in the pasture where he can see us while riding Taylor, but it does not work. I have to let him follow us the entire time which makes it very difficult to work with Taylor.

Many people have suggested I get a third horse, but I hate to add another horse to the equation and make the problem worse.  Any advice? I am desperate.

I do not have an arena. I have two seperate pastures, I try to ride in one of the pastures. I usually saddle them by my tack room which is near the barn and then walk them to the pasture.  I have tried mounting in the barn and walking them to pasture but it hasnt worked out very well the few times i tried. They dont stay in the barn much, I have their stalls open so they can come and go as they please which might be part of the problem.  I should probably go back to stalling them at night, they just get very restless. 

I do need to work on my groundwork  more.   I am unable to devote too much time to them this month and next due to work demands so I am thinking of hiring a trainer to work with them.  They also have severe food obsession issues, which is a habit i am trying to break at the same time.  Thank you for the advice. I will start with groundwork and continue the short rides that increase in length over time.

 This is a tough problem and you may be able to find some good articles online with a search.  Do you have the ability to get them a companion or two -- doesn't have to be a horse, can be a pair of donkeys/sheep/goats/llamas etc.  If you have the space and resources, it has been a helpful solution for some folks with similar issues.  

If you can get help from a trainer experienced with this, that would be my recommendation.  Usually, the separation has to start in small increments and you gradually work them up to longer intervals.  

I have the resources to get them a companion, however I have not been able to talk the husband into it lol  I told him we would try to work on the issue diligently for another month or two, with possible help from a trainer, and then discuss a companion further if we do not make any progress on our own. 

Most of the articles that I have read mention increasing the amounts of time you keep them seperated over time, that is where we are going to start. - we have already been doing this some but not keeping them as seperated as they should be. 

Thank you for responding to my post!
