Lola is coming up for 5 months old and we were due to book her in for her spay. However the vet wants her to ideally be 2kg in weight as it would be better for her operatively. However he has said if things get desperate they will take her in. Lola seems to be stuck at 1.5kg. Is there anything I can do to help her put on that extra 0.5kg. Would increasing the number of meals she has a day help?
