Multiple supporting arguments that dogs raised in puppy mills or similar situations develop behavioral issues.
Environments have a large impact on animals development, especially dogs.
Direct Quotes
"Various circumstances such as poor maternal care, alimentary disorders, physical stress and diseases can negatively affect neuronal development (Chapillon et al., 2002), modifying the activity of physiological systems involved in the stress response and cognitive functions (para 4)"
"It can be hypothesised that isolation is less stressful for puppies coming from breeding kennels than for those raised in home environments per se; this may reflect that isolation, and its concurrent low level of stimulation, is more similar to the normal living conditions of the kennel bred dogs. (pg 7, para 4)
