Hi, I’m Dr. Fiona Caldwell and I’m a practicing veterinarian at Idaho Veterinary Hospital. I’m at home today answering questions from the Pets Best Facebook page.
The first question is, “At what age should I switch my young dog from puppy food to dog food?” I like this question because every dog is a little bit different. If you’ve got a bigger breed dog, like a Great Dane or a Labrador, or something that grows really quickly, it’s pretty important that they be switched earlier than you might think.
Growing too fast with rich puppy food can sometimes cause some orthopedic problems in these bigger dogs so switching as early as four, five, or six months of age in the really fast growing breeds can be safe. A smaller breed dog, like a Chihuahua or Shih Tzu, can typically stay on puppy food longer, but remember that they stop growing quicker than big dogs do and so will likely need to be switched to adult food before one year of age.
The next question is, “My Chihuahua has a soft spot on the top of her head. She’s almost four years old and it doesn’t seem to bother her. Is this common and can it be problematic?” This is really common in Chihuahuas. We’ve bred them to have this sort of cute, domed forehead. Unfortunately, that makes them predisposed for the plates of the skull to not come together 100%. Most of the time it doesn’t cause a problem. If it’s small it should be fine, but do know that the soft spot is basically an area where there’s a little less bone covering the brain so it is important to make sure it’s protected as best you can that from trauma or anything like that.
