I see you mentioned finances being a concern of your husband's (as most do...lol!) but, can I just offer one very important recommendation for the future?
Pet Insurance or a Monthly Pet Savings Account for "future" vetting expenses is probably one of the most important things you can do for your baby!
Especially with toy breeds such as Yorkies, we all here on YT know too well what lies down the road for each of us at one time or another in our lil' ones lives. Don't be caught off guard when the unexpected happens. Especially with a young family of your own...it can really impact your finances if not better prepared. It is not unusual to expect a vetting to run in the hundreds if not thousands.
There are many insurance plans out there but, a friend & foster mom for YTNR did some research on the different ones out there and found 24 PetWatch to be great.
Here's a link to their site:
