Two questions about new puppy...?

Until she gets her third round I would hold off on taking her any where lots of dogs or cats are. If you have a lot of raccoons make sure you look around your yard real well for any packages they may have left. Also make sure that you don't let her chew on anything in the yard. Parasites at such a young age can cause damage to her intestines and stomach. If you plan to walk her at such a young age do not use a collar as you could choke her if she pulls. A harness would be a better safer option. Stop about every hour to let her out of the car for the bathroom. She will probably be nervous so actually keeping her in a crate for transport will help sooth her nerves a little ask the person you are getting her from about two days before you pick her to rub an old towel all over the mother dog and get it stinking like her real well. Doggy totes are something she will have to get used to. Make sure it is well vented and she can see out it clearly. The tote should also not be the only crate she has. If you plant to crate train her at all start right away. A space for home, space for the car and a tote for walking around with. They also make carriages for dogs that can be an easier for taking walks with. With the potty training if you catch her peeing some where mop it up with a paper towel and place it in the box under the chips. Placing a piece of feces in the chips will also make her smell where to go.
