Toy Fox Terrier puppy growth: milestones and weight estimates
How fast a Toy Fox Terrier puppy grows, illustrative weight estimates and the limits of predicting adult size.
TFT puppies grow fast and reach adult size around 9 to 12 months. Because they are so small, a change of 200 g is significant, so weigh your puppy weekly on a kitchen or baby scale and track the numbers. Sudden dips or plateaus are worth a phone call to your vet.
Watch for joint problems, such as skipping on a hind leg for a stride or two, or reluctance to jump. Discourage leaps from furniture, add pet steps next to the sofa and bed, and teach children to sit on the floor before holding the puppy. Falls from a standing adult's arms are a common cause of fractures.
