We Have used the injectable type for years, Giving it orally to our hounds and also yard pets of all types. I have heard that too much would hurt one, But years ago, I had a syringe loaded for all my hounds and the first I gave it to was a pup, Well he jumped just as I was giving he his dose and he got all of it , enough for him and 4 full grown dogs, I thought for sure I would lose him ,But he didn't even get sick. Long story short he lived for 15yrs and was one of the best hounds I have ever had
About the herd dog thing It could be true Im not saying its not,
But two dogs got on noah's boat,
not two of every breed,
I just wonder if the old cokes in the 6oz bottle really did taste better than the ones in the 10 oz bottle
