I'm a bit squeamish so never really given these kinds of things to ddog - she tends to have bonios, smart bones, dried chicken / duck fillets, chews with fruit / veg / cheese / peanut butter in etc. I'd always assumed she was missing out and would snatch my hand off if I offered her a trachea or some other truly disgusting thing.
A friend has bought her a box of such delights (piece of lung, anyone?), and I thought she'd be thrilled...there is a variety of stuff which is all really stinky and she's not remotely interested, just sniffs and walks away. I'm kind of pleased that she's obviously as grossed out as I am, but is this weird for a dog?
