Do Staffies snuffle ?

I am always trying to attribute the behaviour of my cross staffie to either his 'staffieness' or the other half which is unknown. The vet thinks he may be crossed with a collie.

When on walks, he sniffs practically everything, but every now and then he goes into a snuffle mode. The noise he makes is really loud and his nose is practically pressing on the ground and he walks really quickly. Its a bit like those bloodhounds when they are on a trace.

Is this typically staffie?

Thanks. Sue and Chase.

Suki does this because she is looking for something to eat

Moo also does it She was a hoover, thankfully I am beggining to snap it out of her now Xx

Billy is like this too

Same here. I think it is normal
