Rule #1: Get yourself a good vet you can work with.

Training infants of any kind takes extreme amounts of patience and concentration. So, to do a good job of it, it's best to remove any unnecessary distractions as quickly as possible. One of the most distracting things I often have to deal with when I get new puppies is the infamous "D" word, diarrhea.

There are a plethora of reasons why your puppy can get the runs. If you got your puppy from a reputable breeder, humane society or rescue group, chances are that their veterinary professionals will know or can narrow down the causes for your puppy's plight. But I strongly advise against you trying to find the cause yourself. This gets back to what I feel should be everyone's Rule#1 before getting a puppy, 'Find a good vet you can work with.'

I stress that it is a vet you can work with. All doctors have their own style. You need to find one that suits your needs and likes. I like to hear everything down to the nth degree of technical detail. Others want someone who will spare the details, but will talk to your dog with a kind, reassuring voice. You need to do this BEFORE you get your puppy. Rushing to find one while your puppy is running around shooting hot, wet poop everywhere is a big mistake. It will only delay you getting the situation under control and most likely add to your stress level.

Meeting the vet ahead of time also can help you answer some questions you might have about breed, gender and age of puppy to get. This may be simpler than it seems. You would be surprised how many vets will be practicing within 10 miles of your home. Ask your friends. Ask your co-workers. Press them to tell you what they like about their vets and what they don't like. Find a couple of prospects to visit, and go meet them.

I'm a realist. Lots of people won't go the last mile and meet the vet, much as they won't meet a doctor or dentist for themselves before they need them. But even if you don't meet them in person, asking around will find you a vet you will be more at ease with. And if you don't go to meet them, at least call or email and find out if they are taking new patients and what their hours, charges and payment terms are.
