Yes: scale changes what a log protects against
A Flemish Giant can weigh as much as a small dog, and that scale rewrites the purpose of a log. A five percent weight shift that is trivial in a dwarf is a serious amount of tissue in a giant, and the breed's sheer mass loads hocks, joints and circulation every day of a long life. A monthly weight, taken consistently, plus notes on movement and appetite, gives you the long view this breed needs — the slow gain that will burden ageing joints, or the slow loss that a big, stoic rabbit will not advertise by his behaviour until it is advanced.
Weighing an animal who breaks the kitchen-scale method
Standard advice fails here: many Flemish Giants exceed the capacity or the platform of kitchen scales. Use a low platform scale of suitable capacity, weigh him standing calmly on a mat he knows, or weigh yourself holding him on bathroom scales and subtract your own weight — less elegant, perfectly serviceable if done the same way each time. For a young giant, weigh every two weeks and plot the gain: Flemish Giants mature slowly and keep filling out well beyond the age a smaller breed plateaus, so the curve, not a fixed target, is what you are monitoring.
Mobility and feet: the entries unique to a giant
Log what you see him do. Note whether he still rears up for food, how willingly he crosses the room, any stiffness after rest and whether he is choosing softer ground. Check and record his hocks regularly — that much weight on hind feet makes sore hocks a standing risk, and early thinning fur logged in one month is the prompt to deepen bedding before skin breaks. Add appetite and droppings as for any rabbit, but weight-bearing notes are this breed's special contribution to the record, and a vet assessing an older giant will ask about exactly those changes.
Reading years of entries, and knowing the thresholds
The log's value compounds: the entries from his third year explain the stiffness noted in his sixth. Act on trends — weight climbing steadily while mobility notes shorten is a diet conversation to have with your vet early, not after he struggles to reach his hay. Weight loss across two entries, reduced movement, hock sores or appetite change in a giant should prompt a prompt appointment, and any day he stops eating is urgent at any size. Take the log along; dated mobility notes turn 'he seems slower' into a clinical timeline.
Pair each monthly weighing with a short walk note: how far he chose to hop, whether he explored or headed straight back, and how he handled any step or ramp in his space. Giants decline in willingness before they decline in ability, and a shrinking range recorded month by month is a gentler, earlier signal than waiting for obvious lameness. It also gives you something positive to protect — the log is not only a list of problems, it is the record of what his good life looks like at each age.
Keeping a big record in one portable place
Giants are frequently cared for by sitters and boarding homes who underestimate both their intake and their normal — a log stating his weight, his usual movement and his hock history prevents well-meant underfeeding and missed foot checks. Keeping that record in KinsLe's Pet Passport holds his weights, mobility notes and health history together in one portable packet, ready for vet visits, boarding, travel and handoffs across his long life.
