Toy Fox Terrier Ideal Weight Range
3–7 lbs
Toy Fox Terriers have a documented predisposition to congenital hypothyroidism, a condition present from birth where inadequate thyroid hormone production causes disproportionate dwarfism, poor coat quality, and slowed metabolism. The condition requires daily lifelong levothyroxine. FitFido tracks both the dosing routine and weight in one place, making it easier to see whether the condition is stable.
Your dog is more than a breed average.
A generic range is just a starting point. FitFido uses your dog's unique breed characteristics, age, body type, and activity level to calculate their target weight and construct a custom plan that adjusts as you progress.
Please note that a dog's ideal weight depends on many individual factors, including height, bone structure, and overall body condition.
