Congratulations on your new arrival!
Kudos for using Central Illinois Sheltie Rescue, know them well they are great people.
If it's worth anything about adopting 'too soon'?
After 40 years of Danes and all the heartache of bloat, cancer and them dieing before they ever saw 5 years old sometimes.
After the last Dane passed away at 4 yrs old, I said NO MORE DOGS EVER...........
I lasted a whole 2 weeks.
The silence was deafening. :C
Again glad you rescued a sheltie, she is VERY lucky to have found you as her new owners.
