How much can one horse take?

[Bigsmc]

I am looking at Saturday's Tampa card and who do I see in the 3rd race?

Dennis's Dream who ran 6f on Jan 18 (Clm 5k N2Y) and won.
11 days later he is stretching out to 8.5f (Clm 5k N2Y) wins and gets claimed.
4 days later, the great Pernel Bagwandeen sends him out for a 6.5f dash (Clm 5k), wins his third in a row and Michael Thomas claims him back.
7 days later (Saturday) he is going to run 7f (Clm 6250) looking for his fifth in a row (he won at Calder last June).

That is 3 races in 11 days and 4 races in 22 days. I realize he has been printing money for 22 days, but when does this poor horse get a rest?
