How to stop my dog from chasing neighbor's horses and trespassing?

This could be tricky - you need to find some kind of treat or reward that is better than chasing a cow or a horse. You should focus on training a recall command like come, and practice without distractions first. Then introduce a distraction and continue to work on the command.

I'm sorry to hear that you're having this problem! Having neighbor dogs that don't get along with your dog can be very frustrating. From what you're describing, it sounds like the only really reliable solution here would be to put up a fence to keep the neighbor's dogs out. If they are consistently trespassing on your property and attacking your dog in your yard, you can also call your local animal control office to report this - they should be able to fine the owner for not keeping his dogs under control, or even confiscate the dogs if this continues to happen. For your part, I would make sure that you take Sam out on a leash at all times unless you have a fence, so that he can't trespass on your neighbor's property and get into fights.

This is a very frustrating behavior to have to deal with. Sometimes invisible fence works. Other times a tie-down or run system is effective. Another solution is do you have a trainer work with you and your dogs in your home to address this issue. Punishment is a tricky method as it has to be done immediately after the behavior in order to be effective as well as it could backfire and cause aggression.

You will have to keep him on him a leash at all times to start. When he sees something and gets excited and tries to run, then correct him and tell him no, make him sit and calm down. make sure you reward him with a treat when he does this to help encourage the right behavior. Once he does will with this, get a longer leash--like 10-20 feet. He will have more freedom but you can also step and grab it and be in control when needed. Every time he does not chase them, reward him. it does help if you make him sit and stay when you notice the people coming before he does. From there you can let him off leash once he is trained and trusted.

Zeke is a very handsome guy! I see that he looks like an Australian Shepherd or a Border Collie. It's very common for herding breeds to try and chase fast-moving objects like cars. To address this problem, you will need to start with Zeke on a leash at a distance from the road. You need to be far enough away that is able to notice the cars going by without reacting - this may mean you need a *lot* of distance at first, depending on how sensitive he is. Each time a car goes by, praise and reward him with a treat for staying calm. When he's doing well with this, you can gradually begin moving closer to the road, one step at a time. If he gets too excited and tries to chase, just move further away until he can be calm, and work your way closer again. Eventually, with practice, he should be able to stand calmly with you on the sidewalk even with cars driving by a few feet away. It's also important to keep Zeke on-leash or in a safely enclosed area at all times, to prevent him from practicing his car chasing behavior outside of training sessions. It can be challenging to do this on your own in some cases, so if you're still having trouble, I would recommend finding a good reward-based trainer who can work with you in person.

The first best thing you cn do with a territorial dog is invest in obedience training. This will allow you to have greater control over her when she displays her aggressions to those she feels are 'trespassing'. Additionally, makes sure she gets plenty of physical and mental stimulation. Take her for long walks, runs, play ball or fetch, take her with you wherever you can, rides in the car, anything and everything to tired her body and mind. A tired dog is a happy dog. Highly intelligent dogs are often the most anxious and therefore need a 'job'. She seems to have chosen guarding her yard as her job, you need to convince her to choose somethign else as her primary function. Never punish her for being protective as this may escalate the aggression. Try teaching her tricks or tasks, get her a Kong toy to keep herself entertained, even consider a slow feeder or a puzzle feeder to make her work and think about how to get food and treats and therefore keep her mind occupied with matters other than who's in the next back yard. Also, I highly recommend the books by Victoria Stillwell. He training methods are always based on positive training and never punishment.

I'm sorry to hear Sofie is having leash issues. One option to decrease her behavior is when she starts, come to a dead stop and don't allow her any slack on the leash to go forward. Use a short four to five foot nylon leash, not an extendable one. Every time she exhibits this behavior, stop where you are and refuse to go further until she is calm again. With consistency, this can improve leash manners. You can also use a gentle leader or no pull harness concurrently. If the behavior is persistent, worsens or is non resolving I would recommend you reach out to her regular veterinarian or a veterinary behaviorist. Good luck!
