Hopefully soon this cold weather will change. I'm sure in July we will be wishing for a reprieve.
Two thoughts, as if you are looking on the Blog, you have access to this. A company who's new heart medicine we have been using with great success has been Vetmedin. They have put together a website that talks about the symptoms of heart disease. if you go to www.vetmedin-us.com they have some good accurate information.
This is also a time to be conducting a food trial if your dog has had allergic reactions or itching even during the cold time of year. During this time, there are no other pollens or grasses causing your dog to itch, so there are less 'sabotage elements' that are being involved in the test.
Let us know if you need help getting this plan.
