The critical period for socialization begins with walking and exploring the environment. Dog and wolf pups both develop the ability to see, hear and smell at 4 weeks of age. Dogs begin to explore the world around them at 4 weeks of age with these senses available to them, while wolves begin to explore at 2 weeks of age when they have the sense of smell but are functionally blind and deaf. The consequences of this is that more things are novel and frightening to wolf pups. The critical period for socialization closes with the avoidance of novelty, when the animal runs away from - rather than approaching and exploring - novel objects. For dogs this develops between 4 and 8 weeks of age. Wolves reach the end of the critical period after 6 weeks, after which it is not possible to socialize a wolf.[45]
Waterproof. There are varying degrees of waterproof and you may opt not to get the 100% water proof version but we highly recommend having some water resistance for a dog training collar. There are simply too many actions dogs commonly take that accidentally get water on them. They could run in the rain before you get them in or they could splash through a mud puddle. Just the act of drinking their water could slop water up onto their collar without any real surprise to a pet parent. Take some precautions to prevent ruining the collar you choose.
Dogs thrive on a predictable schedule, and setting one up for your new puppy will make life easier for both of you. Feed your puppy at the same times each day to help you predict and schedule bathroom breaks. Schedule post-meal walks, as well as hourly trips outside during the initial stages of potty training. Always take your puppy out after crating, even if was only for a short time, and remember that vigorous play should always be interrupted for potty breaks.
The term personality has been applied to human research, whereas the term temperament has been mostly used for animal research.[18] However, both terms have been used interchangeably in the literature, or purely to distinguish humans from animals and avoid anthropomorphism.[19] Personality can be defined as “a set of behaviors that are consistent over context and time”.[20] Studies of dogs' personalities have tried to identify the presence of broad personality traits that are stable and consistent over time.[19][20][21][22] more on this
