Multiple Yorkies...lot's of fun!
Now the truth...yes, it's lots of fun but, along with that fun comes twice the duties involved with just one. But, not to worry...after awhile it does become routine.
Now that I actually foster for YTNR, I've actually surprised myself at how quick I can prepare meals for four and get them all bathed & groomed in a day!
My two biggest suggestions are:
1. get Pet Insurance on your lil' ones (two pets can qualify for a discount)
2. start an emergency fund for "two" of a minimum $1000 in each
And the reason I put these at the top of my list is because I can't tell you how many dogs come into a rescue for that very reason...the owner couldn't afford the Vet bills & ended up surrendering instead
Best of luck on your quest for a new sibling for Harley
