Our brown lab has eaten many interesting things over the years.
Sheep poo, cow poo, horse poo and her own poo.
Three steaks dh left out on the kitchen worktop.
Three salmon steaks dh left out on the kitchen worktop (because the fool doesn't learn).
A raspberry turnover dh left on the coffee table (see comment above re. not bloody learning).
Two dozen mince pies dh left to cool on the kitchen worktop (seeing a pattern here?).
4.5kg of dry dog food when someone (not me) left the cupboard open. She looked like a barrel on legs, was pooing undigested dog food, and we didn't have to feed her for days.
Numerous tubs of butter and part loaves of bread, left within reach on the worktop (by all members of the family, not just dh).
The cat's food, whenever she can get at it. He prefers to be fed outside, on the patio table, but tends to just eat a couple of mouthfuls and then wander off, and then the dog helpfully finishes it up.
Various rotten things she has found on walks.
A sandwich she stole from an angler - luckily he thought it was funny.
