I have two mixed girls, part border col/aust she, from same litter that are 14. That have had a continuous all day and night buffet of Fromms Gold Senior (Dry). One never gains weight but the other has always been overweight. and now it is effecting her movement. The Vet has sold Hills Prescription Diet r/d (wet) for weight loss. When we try to order it on line then say we need a script from a Vet. Is this true? Also, can anyone suggest a better alternative for weight loss? Thanks
