Becareful where you buy your shots! Some people don't take care of the shots and keep them at the right temp.! I had a litter about 4 years ago that got it 4 of 9 got it they had shots from TSC and the others had shot from the local feed store those 5 did not get it!
Now I order my shots and I have sent one set of 25 shots back to the maker because they were warm when they were delivered! I doubt a feed store or TSC would send there's back!
Very Good Advice...
If you want to try and save some pups you can force feed them raw liver in small pieces and force feed them gatorade as often as possible. It seems to me that if the pup makes it past a few days that they can recover. I have saved some pups by doing this but it has to be a special pup to go thru those extremes. Good luck on your pups...
Dog vaccines need to be kept at the right temp. Also, when buying the shots make sure that you are buying the 7 in one plus coronavirus. TSC in my area only sells the 7 in 1 which includes parvovirus but not coronavirus. Either one of these viruses are deadly to the pups. The 7 in 1 is way cheaper than the 7 in 1 plus corona but is costing a lot more in the long run.
