ok my female Corso is 22 months. Of course upon getting her she received all her shots. Prior to getting her I researched the benefits of two things 1. Raw diet 2. Minimal vaccination shots Both are to support proper health bone growth strengthen the immune system and just overall good health for a longer period of time. In our township we have to the dog get rabies shot in order to have a license. Well today I took her to the vet for annual checkup today. They asked how she is doing of course great. They asked what I feed her told them raw. (The last time I said this they attempted to discourage me) I express my concerned that her period was 9 months ago and I thought it should be every 6 months. They examined her and then said she needed heart worm medication plus a test to see if she have heart worm. Plus another vaccination not one time did they reassure me about her period. All they wanted to do was push vaccination (not needed and heart worm medication which they stated should be given all year) I know this is false cause only need to give during warm season once temp drop below 45 and stay that way no mosquitoes are present. So sad it appears only in it for the money. I will try to find an hololistic vet.
