Hi
I've been a strong advocate for dogs and responsible ownership for as long as I can remember - dogs have been my companions - I show them, train them, belong to dog clubs,etc. Right now we have an 8 year old German Shepherd, and a 3 year old PBGV. I'm also a Mom of a very active 2 year old.
I have to honestly say that I DO understand what you are saying.
My dogs don't get near the attention they used to, but we're all still adjusting. An Aus Shepherd is an EXTREMELY active and smart breed of dog, and when they don't get the attention and training they need, in my opinion, their energies can be overwhelming to say the least. Kind of a situation where even negative attention is attention for them, as their behavior deteriorates. If you're adding in epilepsy, that's even harder. I don't know a lot about epilepsy in dogs, but I do know people that have had dogs with this problem and the dogs were usually put down at a fairly young age.
Also, the taking of food from your kids is the tip of the iceberg - the dog is challenging them for pack position - and if getting away with it, will continue to get worse with growling and snapping.
Have you contacted the dog's breeder about bringing the dog back? I know that most good breeders will take back dogs of their breeding as they want them to have the best situation they can. Sometimes they even have people looking for dogs that are a bit older (not puppies). You may not get your money back as they'll have to put out expenses until a new home is found.
If you really feel the situation isn't going to get better and if your dog's breeder is unresponsive to your situation, try contacting a local Aussie Shep rescue. Sometimes you will hear some really harsh comments, but you don't want you or your kids to be hurt.
When the time is right, and you aren't so busy, adding a dog to your family can be a great addition. Check with some local dog clubs about the breed of dog that would be best for your family - even if you adopt a mixed breed from a pound, the breeds it's mixed from have particular traits that may not be suitable for your particular situation.
Of course this is all just my opinion.....
Hope this helps - good luck
