English Toy Spaniel puppy growth: milestones and weight estimates
How fast an English Toy Spaniel puppy grows, illustrative weight estimates and the limits of predicting adult size.
Puppies are tiny at birth and grow steadily, reaching most of their adult size by around 10 months and filling out fully by a year. Very small puppies need three or four meals a day until about four months to maintain steady energy; weakness, trembling or extreme sleepiness in a young pup is a reason to call a vet immediately.
Some toy puppies keep a soft spot on top of the skull longer than larger breeds, so handle the head gently. Watch the teeth as well: retained baby teeth are common in toy breeds and may need a vet's attention once adult teeth arrive, usually by six or seven months.
