For hound ears, the biggest thing isn't so much pulling them up high as it is bracing the ear leather at the base to help train it to stand up instead of falling over at the base (you'll be hoping as the ear thickens that the brace supports it and trains it to where it can stand on its own). I am guessing with the ear brace, you are putting a piece of moleskin between the ears to pull them up. You want to cut out two pieces of moleskin for each ear, glue one to the tip, the other to right below where you want the breakover. You want to check it against the ear before you cut/glue the piece, as you'll want it to be long enough to offer support for the area where the ear is wanting to break too low. For normal ears, you do not need such a long piece of moleskin, but the ones that want to go hound just need extra support where they're wanting to break down by the head. Before glueing the piece to the lower part of the ear, punch a hole in it, and run a piece of yarn through it. It is more forgiving to do it this way than with the moleskin brace in the center. Once the moleskin is glued into each ear, and the ears glued down, tie the yarn hanging from each ear together, making sure to pull the ears up high. I've found it's much easier to pull the ears up on top of the head using the yarn. Hopefully you've caught them early enough. They're just really tough to fix once the leather thickens :/
Also, you don't have to use the pattern given to you. I've always just used little squares, and made them to fit my dogs ears.
and I wanted to make sure when you say hound ears, you mean they're breaking over close to the dogs head, and not just wide ears. If they're just wide, you don't need to make the moleskin any longer, but then the pulling up high is very important.
