A puppy takes up more time than you have for the first 6 months, training and such. And then joy for the next 13 years. You'll probably end up in a doggy forum than here ;(. I prefer my dog over any hobby anytime.
Actually, I learnt new stuff from his research. What I dislike was how he plagiarised verbatim and insert his own broken paragraphs structure, all in one wall of text without giving proper credit.
