Dog Blog.. digging up bones

Question:

I am looking for a product that I can use on my 11 yr old black lab's ears. She has an ongoing problem with ear wax and odor. We have tried everything from warm Olive Oil, saline, white vinegar, warm soapy water, and used an ear shringe to suction out the ear wax, but her canals are so deep it seems like we never get enough out to even get her comfortable.

Question:

Is there a product made for canines that seem to get Hairballs? I have a longhaired dog that sheds year round that coughs like Cats do that have Hairballs. I really think that she gets her hairs in her throat and cannot get them out. Any information would be greatly appreciated.
