Learn how to dominate you dog. You are the Pack Leader and what you say goes. He is not allowed to dominate other dogs under your leadership. Go to a local obedience class, take lots of structured walks on a choke chain and lead, never off lead. Make your dog work for everything he gets, such as he must "sit" on command before he is allowed to eat his food, etc. Most important neuter your dog if you have not already. He will live a much longer and happier life if you do, as you will cut down his risk of cancer such as prostate cancer, perianal tumors, testicular cancer, etc. I also recommend you watch The Dog Whisperer for good advice.
yes. A dog will walk up perpendicular to another dog and put his head over the other dogs back. This is one sign of dominance.
kill it.
Your dog may lie down when approaching other dogs as a sign of submission or to show that they are not a threat. This behavior can help reduce tension and prevent potential conflicts during interactions with other dogs. It's a natural way for dogs to communicate and maintain social harmony.
There is no easy way to stop dogs from sniffing each other as this is the way dogs find out information about things. A male dog does not go into heat. Only female dogs do.
you just keep it indoors all the time
if you think the dog looks nasty then dont walk by it
A dog that dominates you
Dogs learn about other dogs through the scent they leave. Similar to when people talk to other people, dogs convey messages through scents. A dog that smells another dogs urine, can learn if that dog is male or female, if they are in heat, what the dog's temperament is, if they are healthy or sick, etc.
Probably because it's tired, but there are a lot of answers to that question.
Stop hating dogs.
Fill your yard with killer spiders and other insects. Good luck dog
Cause some dogs like other dogs. Even if it was wet or not probably the dog would still greet the other dog.
