my mean cat

Question
My cat is always attacking the dog. I want to know how to train him to get along with the dog because even though he thinks he is the king of my house he needs to learn how to be nice

Answer
Hi Jaizlyn,
This is not a case of "king of the house."
Is your dog small, large? any chance your dog is overly interested in the cat?
This is a little bit hard to know exact dynamics but you would need to "reintroduce them."
Introduction is the most important part of having two animals cohabitate in a home.
How did you first go about this? Who lived their first?
Attacking is generally due to feeling threatened whether due to territory or in case of large dog clearly of being prey, not "king." Sometimes animals set each other off and we often blame the attacker because we may not see the origin of the interaction, other times it is a reaction from former situation. There could be many different variables that make up a situation like this.
If you have a small little dog it would be your kitty is threatened probably due to territory.
was kitty there first?

Try and be patient,
keep them in separate areas until the situation is resolved, separate rooms is preferable.
After a day or two,
swap their scents, such as bedding so kitty gets familiar with doggy's scent and vice versa.
Allow your cat to see your dog through a window at a safe distance
build positive associations every time kitty is watching dog, he gets played with in a CALM but fun way, he gets affection, he gets toys and yummy treats, he gets gentle, happy, CALM affection. Train his brain to associate positively with the presence of the the dog in sight.
If you dont have a window, and/or the next step would be keeping dog in a carrier in same room so kitty can watch and dog is safe in carrier. He may observe and go up and hiss, but that is normal.
Increase the exposure time daily,
Next kitty can be put in a safe carrier to observe,
they can take turns and do this in little sessions every day.
again, make it positive, they can get treats or their favorite meals when they are safe in their carriers.
Eventually they will be calm in each other's presence. Once aggression has subsided, then you can allow them to interact.
It is up to you to CREATE A CALM REASSURING ENVIRONMENT. The owner or guardian can really change it with proper training to have a very peaceful home.
Good luck, a little patience and understanding that you will he recreating and repatterning a learned and/or instinctive response from your kitty and knowing that it can be done! Try not to get frustrated, and if dont move forward in the steps until you are successful with the prior.
For ex, until kitty is familiar and comfortable with doggy's scent and blanket and not reacting negatively will determine if you move on to the next step. Keep swapping bedding from not before the following day so scent is fresh.
Good luck!
