I had a website on baby... for a couple of months with some relevant content and several eBay sales pages. Got zilch. Never tried anything with the 'dog'.
with 550,000 exact searches a month for dog Supplies and a pretty good ppc , i would say its a excellent domain even with the .info
i say try to sell to end user , i would ask for it in the around low $xxxx area
You could transfer them to GD(maybe get a discout on the renewal?) and use the free websitebuilder they give you with each domain name(they are more useful/powerful than some people think), and you could setup a simple affiliate website and maybe make your reg fee back! good luck.
