How do I get credit for my labor?

I  am a hobby dog breeder.  When I have a litter of puppies, my labor hours are are generally 140/wk for several weeks and then taper off to around 50 hours/week until the puppies go to their forever homes at 8 weeks.   My time is a legitimate cost of doing business, and I should be able to get credit for it somewhere!  Can I claim it as an expense without having to pay income taxes on the amount I claim?  

 

Also, if I pay someone to help me, are they an employee?  Do I have to issue a 1099 and pay employer taxes?  Paying someone to help is generally no more than $150/week and it includes general housekeeping duties that I  can't do because my time is dedicated to newborn puppies.
