Each kit includes 1 syringe and 1 feeding tube.Feeding tube is 16 inches long (41cm) and approximately 3/32 inches (2.7mm) outside diameter. It is best to store your feeding tube and syringe at normal room temperature. In colder temperatures the feeding tube will become rigid and stiff. At body temperature, the tube becomes softer, resilient, and completely flexible. Syringe is 35cc and attaches to the integral funnel end of the feeding tube. The opposite end of the feeding tube has a closed rounded tip with 2 side port "eyes".For Veterinary Use OnlyFeeding Tube And Urethral CatheterSize: 8 Fr (2.7mm)Length: 16" (41cm)This is the same syringe and feeding tube that we use here at Leerburg® Kennels.Here is a link to our formula for tube feeding and bottle feeding newborn puppies: Bottle Feeding and Tube Feeding Recipe.If you are in need of assistance in tube feeding or bottle feeding your pups we recommend contacting your local vet and purchasing our "Whelping Puppies" DVD.Both the feeding tube and syringe are individually packed in sterile packaging and are for single use only.
