Features
A feeding target and an activity plan, computed the way a vet computes them
MuscleBuddy tracks the animals you look after alongside your own training and nutrition: a daily feeding target, an activity plan, and an enclosure check. It describes what the numbers say and hands the decision to you and your vet. It never diagnoses, doses, or prescribes.
A pet is its own record, not a note on your profile
Add a dog, cat, rabbit, or ferret (or record any other animal as a species-neutral estimate) with its birthdate, weight, and a body condition score on the same 1-to-9 scale a vet actually uses. A household can share ownership: a pet added by one person is visible identically to anyone else who co-owns it, not a primary owner and a second-class copy.
Life stage, neonatal, growing, adult, or senior, is worked out from the birthdate every time the page loads rather than stored, because a puppy recorded "growing" and never revisited stays "growing" long after its growth plates closed. The thresholds account for breed size: a great dane and a chihuahua reach adulthood on very different timelines.
A feeding target from body mass, not a human formula bent sideways
Companion-animal energy needs don't scale the way a person's does, so the feeding target uses a different equation entirely: resting energy scaled to body mass raised to the ¾ power, then adjusted for species, life stage, neuter status, and any weight goal. Neutering alone lowers maintenance energy by roughly a quarter in dogs and cats, which is the single largest adjustment after body mass and the reason so many pets gain weight after the procedure on an unchanged feeding routine.
A weight-loss target is computed against your pet's ideal weight from its body condition score, never its current weight, because feeding a loss factor against an already-overweight animal's current weight just prescribes the ration it's already eating. Weekly loss is capped per species: 2% for dogs, 1% for cats, half a dog's ceiling, because rapid weight loss in an overweight cat carries a specific, serious health risk. A pet without a body condition score gets no weight-management plan rather than one built on a guess, and a still-nursing animal gets no feeding figure at all: intake at that age is a veterinary and breeder decision the app has no basis to estimate.
An activity plan built to keep a pet sound, not to train it
This isn't a workout program for your dog. Baseline daily minutes are set by species and size, then adjusted down for growth and for age, and a body condition score of 8 or higher starts the plan short, flat, and low-impact. Two hard limits exist because it's the enthusiastic owner, not the sedentary one, who causes the damage: growth-plate protection caps structured exercise for a young dog still developing, and brachycephalic breeds (bulldogs, pugs, boxers, Boston terriers, Persians, and related breeds) get a shorter, lighter plan with a caution to exercise in the coolest part of the day, because they can't cool themselves efficiently.
Every plan carries its cautions ranked most-serious-first, shown before the numbers rather than after. A neonatal animal gets zero structured minutes and a note that handling belongs to the vet and breeder at that age. As physical activity is scaled back, enrichment minutes rise to fill the gap: mental engagement is how a pet on a restricted plan stays sane, not a consolation entry.
An enclosure check with its own rulebook
Lay out a crate, bed, hide, hutch, pen, food and water station, litter box, scratching post, cat tree, or grooming table on a floor plan, the same drawing tool the gym planner already uses, and get back a findings report rather than a bare pass or fail. Rules cite their source and the citation decides how a finding is framed: USDA housing standards are treated as a compliance requirement in a licensed facility and as advisory guidance in a home, while feline environmental-needs guidelines run as advisory everywhere, since a shared litter box is a real problem for the cats using it without being a violation of anything. A rule that can't be checked, because a measurement is missing, says so explicitly rather than guessing.
Where the pets module sits
Pets is its own space, reached from your own account, separate from Training, Nutrition, Health, and Upkeep. Nothing about it borrows a human record: a pet has a body condition score and a size class, not training days or contest mode, and a human profile has neither. What the pets module reuses is the underlying machinery, the same energy and activity engines, the same floor-plan tool the gym uses for equipment layout, built for a different subject.
If you're managing your own training and nutrition alongside a pet's, the two live side by side rather than competing for the same screen: your program and macros stay on your own pages, and the pet's feeding target and activity plan stay on theirs.
Frequently asked
- Does MuscleBuddy give my pet a medical diagnosis?
- No. Every number here, energy target, activity minutes, weight-loss pace, is a coaching estimate computed from what you record, not a diagnosis or a prescription. Anything that needs a professional judgment call is handed back to you and your vet explicitly.
- What species does it support?
- Dogs, cats, rabbits, and ferrets get species-specific formulas. Any other animal can still be recorded, with every derived number flagged as a species-neutral estimate rather than silently applying another species’ numbers to it.
- How is the feeding target calculated?
- From body mass using the interspecies allometric equation, adjusted for species, life stage, neuter status, and a weight goal computed against ideal weight rather than current weight. A body condition score is required for a weight-management plan.
- Will it tell me how much to exercise a puppy?
- It gives a structured-activity plan bounded by a growth-plate limit, since forced repetitive exercise on open growth plates is a recognized risk for developmental joint disease. It never covers the free play a puppy naturally self-limits.
- Can I check whether my pet’s enclosure is set up correctly?
- Yes. Lay it out on the floor-plan tool and get a findings report citing its sources, including a check for how many animals are sharing one resource like a litter box or a food station.
