Great news for Tiko. And Iris, you are such a good Mommy keeping such a watchful eye on him.
Im guessing that him still humping your arm is not a sexul but dominance thing for Tiko. My friends with neautered males still hump toys and such and continue their pee marking on items.
That was so nice and sweet that you had baked fish ready for him.
It is so wonderful to see all the members here absolutley love their Yorkies and read what they do for them in time of need.
Hopefully you can grab a cat nap today to get your needed rest caught up.
