Doggie delusion

We have a cute chihuahua named Bella and like every other ankle bitter she believes she is bigger than she is, but the part that I find hilarious is that she will sniff her path whenever we go on walks. Not like normal dogs that sniff here and there but like a hound dog, from start to finish her nose is down and sniffing the way. The best is when she gets her nose deep into the grass.
