1. A dosing apparatus for dispensing therapeutic and/or preventative product into an orifice of an animal, comprising: a plurality of interlocking cartridges arranged in a stack, each cartridge containing at least one product, and each cartridge including: a body with a cavity holding at least one product to be dosed,a nozzle which is in communication with the cavity and which is configured for channelling the product to an orifice of an animal, the nozzle being disposed on the top of the body whereby product is dispensed upwardly from the dosing apparatus to the orifice of the animal,at least one piston configured to push product from the cavity, anda recess which is adapted to receive and provide a cover for the nozzle of an identical or similar cartridge; anda dispenser for holding the cartridges and for dispensing product from each cartridge, one after the other, the dispenser including: a magazine adapted to receive the stack of cartridges, anda plunger arranged to drive the piston (s) of one of the cartridges;wherein the nozzle comprises a cannula without a needle;wherein the nozzle comprises a tubular section sized to fit within the teat orifice of a dairy cow for mastitis prevention and treatment; andwherein the nozzle is disposed at an angle relative to the body of 70°-90°. 2. The dosing apparatus according to claim 1, wherein the recess seals the nozzle of the second mentioned cartridge. 3. The dosing apparatus according to claim 2, wherein the nozzle of the second mentioned cartridge includes a resilient collar section at a base thereof which is in sealing contact with a complimentary shaped portion of the recess of the first mentioned cartridge. 4. The dosing apparatus according to claim 1, wherein the angle is 90°. 5. The dosing apparatus according to claim 1, wherein the cavity is cylindrical. 6. The dosing apparatus according to claim 1, wherein each cartridge has a first piston configured to expel the product from its cavity, and a second piston configured to expel a second product from the cavity. 7. The dosing apparatus according to claim 6, wherein each cartridge is configured to expel the first mentioned product through the nozzle, and: only after that, to expel the second mentioned product such that it flows past the first piston and exits the cartridge via the nozzle. 8. The dosing apparatus according to claim 7, wherein the cavity of each cartridge is configured to allow the second product to flow past the first piston when the first piston has travelled to the limit of its range of travel after dispensing the first mentioned product. 9. The dosing apparatus according to claim 8, wherein the cavity of each cartridge includes a section having a greater cross sectional area at the location where the first piston sits when it has travelled to the limit of its range after dispensing the first mentioned product. 10. The dosing apparatus according to claim 8, wherein the cavity of each cartridge includes a section having a reduced radius at a location where the first piston sits when it has travelled to the limit of its range of travel after dispensing the first mentioned product. 11. The dosing apparatus according to claim 6, wherein the first piston of each cartridge has a uni-directional seal which is configured to prevent the first mentioned product from travelling past the first piston and toward the second piston and to allow the second mentioned product to flow past the first piston. 12. The dosing apparatus according to claim 1, wherein the dispenser is a hand held dispenser gun. 13. The dosing apparatus according to claim 1, wherein the magazine has a spring which biases the cartridges towards a breach of the dispenser for engaging the plunger. 14. The dosing apparatus according to claim 1, wherein the dispenser incorporates a squeeze handle for powering movement of the plunger and has a spring for biasing the handle to a non-squeezed disposition. 15. The dosing apparatus according to claim 13, wherein the dispenser has a slide which prevents one of the cartridges, which is in the breach, from being released from the dispenser until that cartridge has had its product contents expelled via its nozzle. 16. The dosing apparatus according to claim 15, formed such that the slide is automatically withdrawn during a reloading sequence of the dispenser. 17. The dosing apparatus according to claim 16, having a blade which moves with and as part of, the plunger to push between the cartridges and assist in separating them when one of the cartridges in the breach has been used. 18. The dosing apparatus according to claim 1, having a hand squeeze mechanism configured to push the plunger to dispense the product from the cartridges one after the other. 19. The dosing apparatus according to claim 1, wherein the plunger is: pneumatically powered;electrically powered; orhydraulically powered. 20. A dosing apparatus for dispensing a mastitis therapeutic and/or preventative product into a teat orifice of a dairy cow, comprising: (a) a plurality of interlocking cartridges arranged in a stack, each cart ride containing at least one mastitis therapeutic and/or preventative product, and each cartridge including: (i) a body with a cavity holding at least one product to be dosed,(ii) a tubular nozzle, sized to fit within a teat orifice of a cow, which is in communication with the cavity and which is configured for channelling the product to a teat orifice of a cow, the nozzle being disposed on the top of the body whereby product is dispensed upwardly from the dosing apparatus to the teat orifice of the cow, the nozzle being disposed at and angle relative to the body of 90 degrees,(iii) at least one piston configured to push product from the cavity, and(iv) a recess disposed on the bottom of the body which is adapted to receive and provide a cover for the nozzle of an identical cartridge in the stack of cartridges; and(b) a dispenser for holding the cartridges and for dispensing product from each cartridge, one after the other, the dispenser including: (i) a vertically oriented magazine adapted to receive the stack of cartridges, the magazine having a breach at its top end for exposing the nozzle of a cartridge for contact with the teat orifice of a cow, and(ii) a plunger arranged to drive the piston(s) of one of the cartridges. 21. A needle-less dosing apparatus for dispensing a mastitis therapeutic and/or preventative product into a teat orifice of a dairy cow, comprising: (a) a plurality of interlocking cartridges arranged in a stack, each cartridge containing at least one mastitis therapeutic and/or preventative product, and each cartridge including: (i) a body with a cavity holding at least one product to be dosed,(ii) a needle-less, tubular nozzle, sized to fit within a teat orifice of a cow, which is in communication with the cavity and which is configured for channeling the product to a teat orifice of a cow, the nozzle being disposed on the top of the body whereby product is dispensed upwardly from the dosing apparatus to the teat orifice of the cow, the nozzle being disposed at and angle relative to the body of 90 degrees,(iii) at least one piston configured to push product from the cavity, and(iv) a recess disposed on the bottom of the body which is adapted to receive and provide a cover for the nozzle of an identical cartridge in the stack of cartridges; and(b) a dispenser for holding the cartridges and for dispensing product from each cartridge, one after the other, the dispenser including: (i) a vertically oriented magazine adapted to receive the stack of cartridges, the magazine having a breach at its top end for exposing the nozzle of a cartridge for contact with the teat orifice of a cow, the magazine further having a spring disposed at its bottom which biases the stack of cartridges towards the breach,(ii) plunger arranged to drive the at least one piston of one of the cartridges, the plunger engaging the cartridge at the breach, and(iii) a slide which prevents the cartridge which is in the breach, from being released from the dispenser until that cartridge has had its product contents expelled via its nozzle.
