can you scratch it (the dry powder) into the soil and water it immediately? I doubt the dog will bother with that much trouble, and it would deliver the fertilizer to the bulb quickly

I would suggest not using bonemeal in any shape or form, if you have a dog.

Years ago, I planted a lot of tulips, mixing bonemeal into the soil in each planing hole. My dogs did not rest until they had dug up every newly planted tulip. I'm thinking that they would do the same exact thing with liquid bonemeal.

Likewise I had always steered clear of fish emulsion and similar products. If I used that, my dogs would probably just roll on the soil, much like they do if they come across a dead critter.

I've been told to just use a low nitrogen fertilizer (for daffodils anyway), if it can be found, otherwise just use some 10-10-10 or something similar.
