Thank you everyone. I've made a list of the things that I need the vet to look at as well as an overall check. Hopefully he'll be able to attend to most things on the list and get her healthy ready for the surgery on those mammary glands.
Nettie had a full assessment from the vet this evening. She's booked in for a scan on Friday morning to check the mammary gland tumours and have bloods taken. Please keep the positive vibes coming for this lovely girlie. She is such a calm and place little girl. I'd hardly know she was here, she's slotted in so smoothly. She's getting lots of cuddles and is being very skippy when I call her to me. She's a delight to walk on the lead... no pulling, she just trots along beside me. I'll update on Friday after the scan.
