Seems very safe for puppies
I had a litter of 5 Pekingese who lost thier mother at 24 hrs old. They were bottle fed, and given this shot at 6wks old. I was very concerned about them having a reaction, never used these shot before. Now, one week later, no reaction, appear healthy and thriving. Am so relieved that I chose to use this product. Although we can never really measure the immune system, I would recommend this product to anyone with concerns over choosing one that is safe! I can also say, these puppies seem more energetic now.
Very pleased with purchase
