I weighed Lily at the vet's again today. To recap where we were:
That was on July 20th.When I brought her here, she was 8 kg or 17.6 lbs (and that was already after I'd been cutting back on her food for a few days, so she probably started at about 18lbs)
After two weeks she'd dropped to 7.8 kg = 17.2 lbs
Today she was 7.2kg = 15.87 lbs
Today she is at 6.6kg so she has again dropped a little over half a kilo in just over three weeks, which is a good steady weight loss.
6.6 kg = 14.5lb
So she has gone from the vicinity of 18lb to14.5
She still is only just beginning to show a waist so I figure a healthy weight for her is about 12.5 to 13 lbs. She still has problems getting up onto a sofa for example due to the excess weight though she is now quite fit, getting plenty of walks.
At her current weight she is the same size as Leo, who is a very compact, solid dog.
