I've put my humane compassion aside & put down some of the metaldehyde
pellets in the obvious places, taking care to cover them or put them in
inaccessible (for pets) places like down the side of the shed and
underneath, and in all the potted plants that are off the ground.
Question is, does anyone have any experience with dogs or cats sniffing them
out and eating them? I don't think my dog (and the neighbourhood cats) can
get to them, but would an animal work hard to get at them? I get the feeling
I'm going to need another application within a week or two, but I don't want
to risk putting them in the best places if the stupid dog is going to eat
them.

There are two types of slug pellets out there - ones based on Metaldehyde and Methiocarb which are potentially lethal to pets, wildlife, children etc. - and Ferramol's Advanced Slug Killer Organic slug pellets which are based on Ferrous Phosphate - which is a form of iron.
These last ones are considered to be "organic" because they are based on a naturally and widely occurring substance (iron) which is not supposed to be harmful to anything aside from slugs and snails. Having said that iron can cause acute liver damage and death in mammals in even moderate doses, so there must still be a risk attached to these too.
I read a post on another forum about a garden hedgehog that was excreting turquoise droppings due to the excessive number of slug pellets it had eaten.
Though this is what the Hedgehog Preservation Society says:
"Although hedgehogs may not necessarily eat the pellets, they are very likely to eat the poisoned slugs and snails and, although these may not be lethal to hedgehogs, they may cause serious internal damage. If you must use slug pellets, put them inside pieces of pipe or under stone slabs where hedgehogs can't get at them. We believe, however, that a "beer-trap" (i.e. a pot of stale beer sunk in the ground) is an equally effective way of killing slugs. In any case, as an extra precaution, all dead slugs should be regularly removed."
Metal (Iron or Aluminium) based pellets are at least as effective as metaldehyde in terms of dispatching slugs, so there's no need to use something as toxic and indiscriminate in it's actions these days.
If you don't want to use pellets there are all sorts of other options depending on how large an area you need to protect. Depending on the size of area/plants that you need to protect barriers can be extremely effective and are much more permanent than any pellets particularly during wet weather.
Spiky things like crushed eggshells, old scourers and sharp gravel are certainly effective. Ecocharlie recycled ceramic shard work even better since they absorb the mucous and stop the slugs getting across at all, as well as being spiky.
You can also use copper bands which give them a tiny electric shock, and placing traps - beer traps, as above, or just pieces of wood, stone, card or carpet that act as shelters - outside the barriers will allow you to collect them in the day time.
Another option are "Nemaslug" nematodes - parasites of slugs and snails that live in the soil & that you water into the ground.
