Our dog struggles with dental sticks and these chewy chunks are just the right size and texture.

Having had numerous teeth removed dentastix are a problem to eat but these are easier for our little lady to manage and enjoy

I bought these treats for my dogs teeth and as a different treat. He eats anything but kept playing with it rather than eating it. He did eventually eat it and I noticed his breath smelt weird, couldn’t put my finger on what it smelt of, until I gave him the treat the next day. It smells toxic as though it shouldn’t be anywhere near a dogs mouth. What on earth is in these things?? He wouldn’t eat it this time. Slightly worried. Is this normal??
