i used to go to the vet when i was little but as i grew up i started giving my dogs their shots by myself, only the rabies i still go to the vet so i can get a certificate that it was given. i dont know the quality of that brand, but do a research about it and maybe if you feel comfortable and get practice (not on dogs of course, maybe in oranges or something) than you can do it yourself, its WAY cheaper, but you have to know what you are giving them.
