I have a 4 year old Siberian Husky that we just got 3 days ago, he will chase cats (which I understand why) but I try to take him for long walks and would love to get him to run with a bike, but he will also go after horses, and cows, any thing that moves, is there anyway I can get him to stop going after everything?

I would suggest start small on foot and with treats. This way you can have a precise amount of interaction with him and begin teaching commands for left, right, on by, whoa, etc.

Have really high value treats on hand and reward for successfully obeying commands.

Then just work your way up towards active pulling with less direct interaction.

What Seattlesibe said ^

Also, it may just be an acclimation thing. If he hasn't had much interaction with other species and he's full of energy, *everything* is probably potential chase/play material. Oh boy! Horse! Oh boy! Cow!

You may find just hanging out near them for a while where he can't chase them (on lead, or in an enclosure) helps wear some of the newness off.

We have elk where we live, and when we first moved in our husky would run up and down the fence line barking at them and playing with the calves (who liked a good romp as much as Vikhr did, much to their mom's displeasure). However, as time as gone on, he does it less and less. It's more "Oh, I see the elk are here tonight. Very nice." and goes back to nosing around.

I'm not saying he wouldn't chase them outside the fence if we were close enough, and I'd still keep a sharp eye on him while on my bicycle. But it's not the foregone conclusion it used to be.

You have only had three days so in his mind he is not your dog yet. This does give you an empty slate to work with so to speak. He knows what he could do with his previous owner but you are new and can teach him what YOU expect of him! Four years old or not I would start with basic obedience, this would help in trust and bonding issues that will need if you plan to run him later with bike, sled, or ski's. If your not sure how to start find an excellent trainer (many trainers out there, get one that knows what they are doing) and consider the monies you spend on this to be well invested in a long happy future with your dog  

As Jeff said, high value treats work well! Hughie is also bang on - training / basic obedience goes along way. Look for training that isn't in a busy place, and smaller class sizes (10-12 dogs). Easy Walk harnesses are great for walks - for off leash events I generally suggest taking the harness off. Taiga is 100% right, everything right now is new and exciting - hence the pulling! Over the coming weeks you will see adjustment in behaviour as the bond between the two of you grows!

Don't get frustrated, just as you are adjusting so is he and this is a great time to set expectations. He will tell you things he needs and you will tell him things you need. Dogs love routine and regularity. Right now is the best time! Although trying, this is when you shape each other and the relationship you'll have for years and years to come!

All the training suggestions are great.

You could also try a pinch collar or no pull harness (easy walk, wonder walker, etc.) as a temporary fix until you are able to implement the training. You will probably have trouble getting him to focus on anything until you get some of the crazy out. Using one of these tools would help you be able to safely get that energy out, and then you could start working on your training sessions following the energy release.

I think trying to get him to focus on training with all that pent up energy is going to be almost impossible.

My impression of the OP was that she wanted the dog to pull just to not be distracted by other things, essentially how to train the dog to focus and stay on course??

Is this right? You weren't interested in stopping the pulling per se, like on walks?

Either way, it's basically the same advice.

The right equipment, treats, patience, corrections, and praising obedience to the commands.

Ah good point Jeff. If that is the case, you're 100% bang on.. as with anything practice makes perfect. Patience and consistency is key.
