Training

Question
We recently adopted a Cockerspaniel from a freind who no longer was able to care for him, he is a year and a half year old neutered male.

He pulls on leash, and jumps on people, we pull him and say NO, but then he growls and barks at them. Should we have a different collar? we have a choker type, that pulls smaller when yanked. Also how can we have him be nice to other dogs. He is a wonderful dog, and we love him. He is great with my kids. but don't want him to jump on friends. Your help would be greatly appreciative . thank you

Answer
I covered part of your question in my last answer.  The choke or slip collar is a common tool.  With proper use, most dogs do fine.  Some dogs need a little more.  If you walk with the dog on the left, pull the chain through one loop forming a "P". Facing it, slip it over its head. The free end should come over the neck to the leash, and the other end should drop slack when there is no pull on the leash.  Easier dogs will give up their pulling with a few good snaps of the leash
combined with a stern "Bad dog!".  You can work up to forceful corrections
with the leash doubled up in both hands and your whole body behind it.  But
you don't want to use any more force than you need.  One gentle technique I
like is to just stop when he pulls.  He wants to go.  If you move forward when
the leash is slack, and stop when he pulls, he should quickly figure out the
only way to get to go, is not to pull.  This is about teaching him not to
pull, not getting somewhere.  The man that taught it to me said "If in a half
hour you haven't made it out to the front walk, fine, you have taught him a
lesson.

Still, you may want to switch to a head collar.  The leading brands are Promise,  Haltie, and Gentle Leader.  They have a strap going around the dogs nose looking something like a muzzle.  They work by pulling the dogs head around.  No other way gives you such great control with so little force.  The prong collar is now a
dangerous relic of value only for its macho looks.  Do not consider using one
without hands on instruction from somebody with plenty of experience with them.  Many obedience instructors insist on them.  As long as they can fit them properly, it shouldn't be a problem.
