I know that cockers come in all sizes , and our two are both from 'large stock' so we expect them to be on the heavier end of the scale around 17/18 kg but notwithstanding that I have decided that Gracie is a little too pudgy for her age!
She just turned 6 months old anyway and weighed in at 15kg a day or two ago, so we've decided to take her off the puppy food and put her on an adult formula and reduce the quantity that she gets also. + I'm walking her 2 times a day instead of just once.
I really don't want her to have weight problems - Our 8 year old Bailey is on Eukanuba weight loss formula because he stacked on 3 kg recently - he was always 'free fed' but we think he started stress eating when we bought the little one home
Hopefully they will both be back to a more reasonable weight range in the next few months
