This makes no sense… by the way vaccines for Lyme have been around for 10yrs. This doesn’t make sense unless you can mass vaccinate ticks.

Veterinarian here and my answer would depend on your housing situation and the breed of dog you’re getting. Like if you’re getting a small toy breed and you live in an apartment maybe get some pee pads ready and start brushing teeth as young as possible…

Most universal recommendations would probably be small dehydrated liver bits for training in a tightly sealed bag you take with you wherever you go. Almost everything else can be situational. For difficult large breeds with prey drive that live on property I see a lot of success with e-collars / training collars instead of a leash. Don’t want your pet to think every chance off a leash is a chance to escape and be free.
