Antibiotics and such

I've found that there is a place for injectable antibiotics, but i agree, oral antibiotics are much easier to give and easier on the dog, as far as having antibiotics given. But an intra muscular injection gets the antibiotic into the dog's system quicker and i believe has a better effect than oral antibiotics. If u have an infected wound, injectable penicillin will clear it up in 3-4 days. Oral will take longer. Also, my kennels are away from the house, so at times, it's easier for me to give a once daily dose of injectable as opposed to several oral doses. There are risks involved with intra muscular injections, u could hit a vein or artery, or u could inject into a nerve. Sub-q injected antibiotics , i feel arent as good as intra muscular injection , better than oral administration. Sub-q injections also carry risks of site infection, i've seen some incidents where the skin sloughed off at injection site. On a seriously cut dog, i'd go injectable and maybe even over cover with oral, you'll be using the oral for like 10-14 days and injectable for 4-5. .but i always refer to Merck veterinary manual for each individual episode so i can cover for whatever potential infectionwith correct doses and duration. Mrs. Louisiana is a vet employee, i hope she'll elaborate, its been 30 yrs since i worked for a vet, things may have changed since then
