We are having the same problem & they definitely do not look or act like fleas. They are located primarily on their bellies. What are these things? We are going to start using tea tree oil & see if that helps...
Hi. I have the exact same problem with my Jack Russell Terrier. Have you figured out what the bugs were/are? Thanks for your help!
There was another recent post about flea problems, and the unique solution of bathing the dog with Dawn dishwashing liquid was mentioned. The person had been having a horrible time with fleas and tried everything on the market to no avail. He posted back to say that the Dawn worked! Since Dawn is used for any animal who gets stuck in an oil spill, I would imagine it's safe enough for a domesticated animal. Might be worth a try.
You two may be right, I saw one jump today. It was smaller though, not like the first ones.
Here's an interesting article on cat and dog fleas, complete with pictures. Like peekawho, I think it's fleas.

Sounds like fleas to me. How large are you talking?
