how big are they? one is a lionhead x lop, and other is a lop, could be mini or dwarf depending on size
Muffin (lop) is 3105g and Punky (lionhead) is 3230g.
Also, they don't seem overweight and they're active but what weight is the average for those breeds?
I think they are a bit heavier than is average for those breeds. Dwarf lops are usually around 2-2.5kg, lionheads 1.5-2kg normally I think. Where did you get them from? If they are pet shop/back yard breeder/ mass breeder bred they are likely to be a bit of a heinz mix and wont be a pure breed and so wont conform to weight standards. It is best to just get them checked by a vet to see if they are over/under weight, as weight alone for mixed breed rabbits isnt really an indicator of whether they are a good size or not, if that makes sense.
I bought them is a pet shop.
My vet has said that they're average weight/size and that they have no health problems from their size,
but couldn't confirm exactly the breed was as I said I bought from a pet shop.
Should they be put on a 'diet' to bring the weight down a bit?
