Crysler Animal Hospital Almost killed my dog Independence MO

I visited the facility for the 3rd time for my dogs heartworm shot.  Within one week he was horrbibly sick and lethargic.  I was panicing.  Then my girlfriend and I remembered the last 2 times we went to the vet for heart shot he was very ill and we had to take him back for another treatment and of course another large charge. 

So I went to the vet location and asked them to pul up the chart for my dog. Sure enough, the last two times we were back in in a week for medication.  I have repeatedly called to visit with the vet but they will not call me back with a prescription for heartworm that I can buy online.  These people are very cunning crooks who lul you into a false sense of security with your pets but they are nothing more than a chop shop for your pets....not doctors for sure.  AVOID!!
