Serena Williams just had 'weird tasting' dog food

Serena Williams' keenness of tasting her dog food turned out to be the biggest goof up she has ever made.

The 34-year-old tennis pro, who is currently in Rome ahead of a match, decided to take a little nibble from her Yorkie's gourmet dish while lounging in her room, E! Online.

In a clip that Williams posted on her Snapchat, she was heard saying, "The best thing about Snap is I don't have to hear anybody hating or trolling, 'cause I think this is something you definitely wanna hate or troll on. So they have this menu for my dog, because Chip left his food, can you imagine?"

She continued to explain that the night before she ordered her pup some beef with chicken and vegetables and it looked delicious.

"So today, I was like, I might wanna taste his food, so I order him the salmon and rice because I eat salmon and rice. Before you judge me, look at it. It's kinda all mixed together. C'mon, it looks good...I put some in his bowl. I'm like, what the heck, I'm gonna try a piece. So I ate a spoonful. Don't judge me, I ate a spoonful," Williams continued.

Revealing how she felt after eating the dog food, the tennis pro said that she ran to the toilet thinking that she will pass out as it tasted weird and she force-swallowed it.
