Hi Trisha,
Sorry to hear that this is difficult for you. Currently, we don’t have a video on proper subcutaneous injection but it’s on our list. For now, I would recommend that you call your local clinic and ask to see one of the registered veterinary technicians. It would be free at most clinics and let them know you just want a lesson. Aside from that, I suggest you search for other videos online. The drug you are likely referring to would be Convenia – it is an injectable antibiotic that lasts 2 weeks (I’m neither supporting or endorsing the product, I’m just assuming this is the one you’re referring to because it is common and matches your description but I can’t be certain). You will need to be prescribed this by your veterinarian and they will calculate the dosage. I don’t give out that information for liability reasons. I know you’ve given me the weight but it could be wrong and I can’t take that risk. I also can’t be certain about the specifics of the product you give. Your veterinarian will certainly advise you on this as they are the only source for obtaining this medication.
I hope this helps. Thanks for checking out the site!
Dr. Clayton Greenway
