How much to feed 5 month Newfoundland puppy + heart murmur question?

Hello,

I have had my Newfoundland puppy since he was 10 weeks. I was informed from the breeder he had a 1/2 grade heart murmur. I have been checking up on it every 2 weeks and it is still present. When should I plan to bring him to the cardiologist? I don't see any symptoms of heart failure or abnormalities. I plan to get him neutered around 1 year so I'm wondering if I should go to the cardiologist around 10 months. Like I said I do not see anything strange with his breathing or activity, but also want to be safe rather than sorry. I know a lot of (large breed) puppies have this problem and I'm not overly worried quite yet. Also, how much should I be feeding my male puppy? I heard a million things. Right now i'm feeding 2 1/4 cups 3x a day. Is that too much or too little? He recently had a big growth spurt.

I will give you info based on my personal experience with another giant breed, Great Danes.

I know many responsible breeders of dogs with genetic heart disorders will utilize health testing on adult dogs prior to breeding. OFA.org is where you can find results on some of these tests. I've heard of potential show dogs being tested young to get a preliminary rating, formal ratings aren't given until about 18mos or so. You should ask your breeder about what you need to do. If they are health testing their dogs, they should be able to tell you what you need to do in the future. A good resource is the ofa website: https://www.ofa.org/diseases/other-di...

Regarding feeding, again, this is a question for your breeder. They should be very familiar with the type and quantity of food that is best for their lines. In fact, many breeder contracts specify what should be given. Special attention is given to growing giant dogs, because too-rapid growth can lead to bone problems.

Your questions about the heart murmer should be discussed with your vet as their is little assitance anyone in this forum can provide to you. Also how much to feed your pup depends on what type of food you are feeding them and I would recommend you also discuss proper feeding amounts with your vet.

Excellent response... no breeder will know more than your veterinarian. With a breed you don’t see every day, you need a good relationship with your veterinarian and start now.
