DIY pet health check

The most common form of diabetes is diabetes mellitus which means that the pancreas has either stopped producing or has significantly reduced its production of a hormone called insulin. It is this hormone that regulates the sugar levels in our blood.

We all want to keep our pets healthy and happy, do you spot the signs if something is wrong? Here at The Pet Vet we recommend giving your pet a nose-to-tail check (MOT) and if you notice anything listed below marked in red, give us a call to book an appointment for a check-up with a vet; if you do find something don’t worry, in most cases, conditions are easily treatable. Make your pet’s check a happy, positive experience for both of you by giving them lots of fuss, attention and a fun game afterwards. Remember white points are good, red points may need further investigation.
