A righteous man provides for the needs of his animals. PROVERBS 12:10
During the nursing period, a puppy receives protective antibodies from the mother's milk. This natural immunity will begin to disappear with time, and may be gone soon after weaning.
Around 8-10 weeks of age, a puppy is susceptible to a number of diseases. That is why it is so vital to take your puppy to a veterinarian as soon as possible for a check-up and vaccinations, regardless of where you bought your puppy.
All puppies should be vaccinated against canine diseases, checked periodically for worms and other parasites, and given an annual medical examination. If you buy your puppy from a breeder, the breeder has already started the series of vaccinations and wormings.
When selecting your veterinarian, make an appointment to go in and talk with him or her and use your own judgment or first instincts. You may ask for references also, as you want to be very comfortable with the veterinarian that you choose. If you were to go to a human medical doctor and you were not comfortable with them, you would not continue to go to them and this is how you should feel about your animals also.
Many people use the same veterinarian that they have used in the past if they have had a pet previously. Or even more people talk to their friends about the veterinarian that they take their pets too. Just remember no matter who you pick, that they can make mistakes, just like any other human. You want someone who will be able to walk into the room and start talking instantly to your pet and if they have a calming voice or not. No matter if you own a cat or a dog, these animals are intelligent enough to know where they are going as soon as you get to the vets office. Many become stressed just seeing the parking lot or the building. And then there are those others, that just love to go to the vets.
Perhaps the most loving, responsible thing you can do for your pet is to see that he/she receives timely health care from a veterinarian. His/Her life depends on it. Also Spaying / Neutering your puppy can prevent your new family member from some forms of cancer. Talk to your veterinarian regarding the benefits of spaying and neutering and at what age to do this.
