If you like to eat the meat from dogs, then you like dog.
If you like to play with/take care of/pat them, then you like dogs.
This is the same for other animals which are countable (have a plural form), such as cats, rabbits, chickens, lambs (baby sheep), etc. For example:
Whale isn’t sold in most countries because whales are an endangered species.
There are a few countable animals that have a special name for their meat: pork (from pigs), beef (from cows), veal (from baby cows — called ‘calves’), mutton (from adult sheep). Therefore, people don’t say “I eat cow; they say “I eat beef”.
In contrast, fish is uncountable. So it could mean either the animal or its meat. For example:
Fish is sold everywhere because people believe that there are still plenty of fish in the sea.
如果這篇文令你為所有動物感到難過（不僅僅是烤狗），但你還想吃一些肉，那麼你可以考慮吃雙殼類（牡蠣，青口貝和蛤蜊），這個選擇更合乎道德的。與哺乳動物不同，它們沒有大腦，故不害怕死亡，也不會感到痛苦。If this blog makes you feel sad for all animals (not just barbecued dogs), but you still want to eat some meat, then you should consider the more ethical choice of eating bivalves (oysters, mussels, and clams). Unlike mammals, they have no brain, so do not fear death nor do they feel pain.
