Plan on your new pup having some accident in the house. Him waking you up during the night. Chewing something up, when you thought you were watching him. Latching on to your skin/clothes with those needle teeth playing.
Leash, collar, crate, treats, toys, and bedding that will likely get shredded. Product to clean up accidents, non detergent puppy shampoo.
Tons of patients. Just enjoy your pup, and keep in mind they have a short attention span.
Puppies need safe socialization, not dog parks.
Not all those who wander are lost.
Life is just a leap of faith.
Spread your arms and hold your breath and always trust your cape.
Two things define you. Your patience when you have nothing, and your attitude when you have everything.
