PETZ: TDH Holdings...pet stock diversify.

The Pet stocks I have featured in this and my first five posts, offer diversity to nearly any portfolio: in terms of sector, geography, etc. My research is haphazard and does not pretend to convey a depth of knowledge. Instead, I ask for your input and indulgence. I have not encountered a 'Pet' ETF, would welcome leads on other recommendations in the 'space.' Thanks!
