Jerms, people are upset because there are a lot of flippers out there and the pups do not receive the best care in the world. Yes, breeders can make money if you look at just the money they get from the litter. People who say they can't are usually under the belief that the breeder is keeping the number of litters down and the proper tests done. Still, even if you look at a litter of 7 pups, we will do labs since this is the breed I figured out originally, with the help of a breeder, the costs of food and care of the pups from birth until they go to their new homes (if they are all sold at 8 weeks), the average amount of money you make for a litter is 79 cents per hour. Yeah, they may get it in one big cheque at the end but what other job do you make so little.
Not to get into the fight too much but just to give you an ideal on the costs of breeding some breeds over others and why some are more expensive. First, my parents bred pomeranians so this is going from their background. Also, this was many, many years ago so the price they made for a puppy was about 650 per pup. Fees to register every puppy is something around 20 to 40 for the puppies. Microchipping ranges where you are but can cost upwards of 80. A pomeranian produces a litter of 1 to 6 puppies, the average being around 1 to 3. Out of all the years that my parents bred poms, we produced one litter of 6 puppies and they were all stillborn. The rest were usually 3 or under. So, when you look at the puppies, you have paid out 300 for three puppies to be registered. Food costs will be about 100 for the 2 months, including the food for the dam. There is 400. Vet appointments can range depending on the female. If you are delivering naturally, you will usually get an x-ray $85 and if you are c-section, you will get a confirmation by ultrasound $35. Overall, you should look to pay at a minimum, 200 for vet care (and that is a really low number, I can't even pay that little just walking in the door). So that is 600, nearly the cost of one pup. That doesn't include your time, the health tests that should be done and so on. Health tests for a pom is hip dysplasia ($270), eye clearances($60), Patellar Luxation (not sure of the price on this anymore), and heart exams (about 100 to 150). So for 3 litters, you have just spent $2735.00. That is if everything goes as planned. If all three litters only produced 3 puppies each time, you made 5850 in total or 3115.00 in profit as you say. I also forgot to take stud fees into account if you use a stud so you are looking at about 2000 in fees for three litters. Since every litter is a 16 week commitment (starting from breeding) and you say you work 40 hours a week for the litter (which you spend a lot more time on) then you make $4.86 per hour. If you have to cover stud fees, you make $1.82 per hour.
So yeah, that is just poms at 650. Labs have a higher feeding cost, they require hip and elbow clearances and eye clearances at the least. There are a few other clearances you can get. Stud fees can range but are usually around 800 to a 1000 and pups sell for between 600 to 1000. The higher expense, as well as supply and demand factor in the cost.
Bulldogs (I have experience here too, although I haven't bred bulldogs), have to do AI for every breeding. Many breeders learn to do it on their own so I am not sure how much it costs to get a vet to do it since the breeder I know does collection and administering herself. But she does have to pay for progesterone tests, which is 80 per test. Then the pups are always delivered via C-section, and it is usually 1500 (more or less). Stud fees are 2000 to 10000 (and yes, she paid 10k for a stud, she purchased him). Litters can be 1 to 10. Ten is rare, 1 is more common so often the high costs of the puppy helps recoup loss when the litter is only 1 or 2 pups. Don't forget that you also have all the other medical and care costs. There are about 10 clearances that you can get on a Bulldog and there are three that should be mandatory. So again, the higher cost.
Pet quality and show quality are often sold slightly higher simply because when you purchase show rights, you are often paying for BREEDING rights. When you purchase a show quality pup on a pet contract, the price is the pet price. A show quality puppy can be sold as a pet while a pet quality pup is never sold on a show contract.
Sorry for the long email, just wanted to explain why some breeds are more expensive and the difference between show and pet quality.
