Dog question

[bigoleworm]

So I am a failed foster home. The two beasts we were going to foster for two weeks are officially our beasts. (We have had them for two years, this is not new news, just background info)
Anyway, our one dog hates men on any wheeled device that come near me or my boys. By wheeled device I'm talking bicycle, skateboard, scooter. Not baby carriages, those are okay, even when pushed by men.
How do I get him over this? We tried having our son ride his bike near him, but he doesn't care about bikes when our kids are the ones riding them. It's just strangers.
And he goes nuts. Like back flipping barking his fool head off nuts. Oh and the bikes don't need to be near him for this reaction, the can just be in his sight and he goes nuts.
Both of the beasts are lab mixes, they weigh about 75 lbs each. And much like my human children they are the best of friends one minute and bitter enemies the next minute. The only difference between the humans and the hairy ones is that the hairy ones occupied the same womb at the same time.

You need to look up trainers in your area that specialize in behavior modifications. My dog would go nuts to get at another dog when on a leash so much that he would lash out at his furbrother to transfer the anger. I paid someone waaaay too much and 12 weeks later, we can calmly walk past dogs if they don't get too close and I keep calm. They used specific dogs and other trainers to assist in walking by and modifying the behavior.They will also train you. Naturally, I would get anxious when seeing other dogs approach and my dog was feeding off of my emotions. So I had to work on myself as well.

I have a rescue Dachshund who barks and growls like crazy at anyone other than my husband and I. He's actually nipped at the back of visitors legs a few times as they were getting up to leave. We've begun working with a trainer and he's gotten a bit better, I'm hoping we can resolve this issue completely. It's been hard to change, I was used to having him sleep in the bed but our trainer has us crating him at night and he's also no longer allowed on the couch. We're also working on some basic commands to start (he walks very nicely on a leash but doesn't know anything like sit or stay) and I'm sure we'll move on to some more challenging things later on. I'd be happy to share the initial instructions our trainer gave us (we've only met with him twice so far) if you're interested.
