Try to get a photo of the dog in your yard if it happens again(video is better) and make a journal of when the dog gets in your yard if it happens again. Now that he's done it once(that you know), he may make a practice of it. I would call AC, report it and ask them how to keep your pets safe from this animal aggressive dog that his owners are not able to keep in their yard. He could easily get out and run the neighborhood, too. Animal Control will likely go meet with the people, educate them on their responsibility and explain what will happen should they have a second complaint, which will probably be an expensive ticket to start. I pray that you can keep your babies safe from that dog but be prepared to defend them should he come over that fence. It might be wiser to take them out one at a time for the time being so you can grab your dog up if he comes over the fence - which he probably won't do with your there.

I use a big huge black automatically opening umbrella to whoosh open when out walking my dog and it very quickly intimidates most dogs into keep quite clear of me and my dog. That big thing whooshing open before their eyes and making me a big target suddenly tends to really take the "attitude" out of most dogs and they quickly lose interest in approaching me and anything near it. In fact, most turn around and go the other way quite quickly. I would probably take one of those outside with me in the future when I took my dog out to potty, along with whatever other items I thought I'd need to keep my dog safe.
