IRIS pen: a great playpen for your puppy - put bedding in half and either a litter box with pine (Feline Pine or Equine Pine) pellets or pee pads on the other half. Whenever you can't watch your puppy, make sure he or she is in the Iris pen. A great way to teach the puppy how to be clean or hopefully continue the good practices your breeder has started - many breeders use these and they are a great idea for a new puppy.
Nutri Drops: this is my new favorite stuff for a puppy who might be stressed or sugaring out. ALWAYS have this on hand and take with you when you travel with your puppy. I prefer this to the other treatments because it works instantly. I have never seen anything work better than this stuff.
We feed and recommend Royal Canin. I prefer not to use the Chihuahua but the small or x-small puppy and adult. For puppies and any adult dog who is having trouble keeping weight on, food is available at all times.
