First of all, I want to say that I have never worked with a Boykin spaniel. So, it’s entirely possible that there is some different characteristic in this breed, that you have to address. But I will tell you what
my thoughts would be, if I were seeing this with a Lab, Golden or Chesapeake.
1) Looks like a “soft” dog. This is not a bad thing, just understand that this animal, in a new venue, immediately became concerned about making a mistake and possibly receiving pressure.
2) Generally, there is a lack of confidence and momentum on the lining. A “normal” ratio of lining to the back pile vs. stopping and taking a cast is 4 or 5 to 1. That ratio usually maintains momentum. So something in this dog’s mind or genetics is a bit different.
3) In your description of prior training, you mentioned that you did FTP to the point of boredom. It may be that too much pressure was applied and you saw the results of that, not just boredom. FTP utilizes direct pressure (vs indirect pressure). There is always a risk with direct pressure that if it's overdone, the dog will eventually begin to question if they are really doing what is required to avoid/turn off the pressure. A little bit used wisely is the way to go.
4) I would not force on back on the T or TT in this situation. There is a school of thought that says the speed/style you reinforce, is the speed/style you will ingrain. Also, if #3 is correct, more pressure now, in this setting, would be bad. Also, this is somewhat new to the dog. We would not
be justified in using force for something new, we are teaching, showing and repeating.
5) I would expect more style/speed by putting birds on the pile, and this reinforces my guess that #3 is correct.
6) So, what to do,, use birds on the back pile always. Minimize the repetitions on the T and TT, do the drill on successive days, but keep each day’s session short. With birds on the back pile, send 2 or 3 times, do a stop and over. 3 or 4 more times, and another stop and over. Then 2 times all the way and quit. Keep in mind that the end goal is to teach the dog to handle on blinds, not to do the drills.
7) It will probably take more calendar time with this dog given what you’re seeing and where you’re at, but you don’t want to sacrifice any more style to get the job done.
8) Maybe think about starting to teach pattern/permanent blinds sooner. You don’t use pressure in the teaching, and this generally helps momentum. Another approach is what some call the Chinese drill. No e-collar pressure on this, use “no” and show/help handle the dog as required. At this point going
forward, you need to make the dog understand that nothing bad will happen if he gets stopped, verbally corrected, and shown what you want.
You should see a gradual improvement in momentum style and speed with this approach. When he looks tight, worried and is not having fun, believe your eyes and help/teach/simplify and you'll both have more fun.
9) Having said all that, there are some absolutes where pressure is still mandatory and should be used - no gos on these types of drills is one example.
