<human>: Can you succinctly summarize the text in 1-3 sentences?

First for some background information, I have a beagle-lab mix and hes about 3 years old now. He grew up around cats and he never had a problem with them when he lived with cats. When we moved out of our grandparents house it was just my dog and no cats.

Now my neighbors have a cat and they have been bringing it outside more and more lately as the weather is getting warmer. My dog goes nuts anytime the cat is outside and I feel terrible because I feel as if the barking bothers my neighbors and I'm worried that if my dog were to get out he might try to attack my neighbors cat.

Does anyone have any advice to help calm my dog down when the cat is outside, currently I try to go outside and throw the ball and play with him so that hes not paying attention to the cat so much but that doesn't solve the problem.

My dog barks at everything but is usually friendly to other dogs and people, hes gotten out of the yard a few times (he learned to jump the fence so we raised it by 2 feet) and hes never gotten into trouble other then running around the neighborhood. But with this cat he just goes nuts.
<bot>: My dog hates my neighbors cats and I am wondering if there is any way I can train my dog to be less aggressive towards the cat.
