I used to think it was disgusting that occasionally my Spaniel got small slugs on his ear (the risk that comes with long dangly ears and them wanting to stick their head in undergrowth, I suppose).
Then I got my second dog and he swallowed a dead dried up toad whole before sicking it back up at my feet.
I didn't think anything would trump the toad incident in disgusting/freaking me out. Then today my dog came in from garden with a tick on his head. It looked like a nasty grey growth. I didn't even know ticks could be grey. Ticks are disgusting. I still feel queezy. I can't believe it was in my garden! Yuck. Yuck. Yuck.
This is the stuff no-one tells you before you get a dog!
On a side note my vet removed it for me and very kindly didn't charge me anything.
