Anal sacs, and a couple of tips!

Here's the question:

Romi had a funny fishy smell one day last week, so I looked it up on here and found it might be anal sacs and decided to call the vet the next day. Next day the smell had gone. Does that mean it sorted itself out? Should I take her to the vet anyway, or hang on to see if it happens again?

And a couple of tips I got from my great trainer:

We weren't very good at recall, so I trained Romi to touch the palm of my hand - first from very near, then moving it round and then from gradually further away. She now comes running to me when I hold out my hand and say 'hand' - well, most of the time;-)

And to give her some mental exercise or when we can't get enough physical exercise because of the weather (and after she was speyed, when she had stitches still) I put some tasty treats (smelly ones) inside scrunched up newspaper sheets. Just a tiny bit in each sheet and some scrunched up with no treat. Make a big pile, show the dog, stand well back and watch the paper fly! There'll be scraps of paper everywhere, and it's no substitute for a good long walk, but Romi loves it and it keeps her busy for 15 minutes or so.
