There is no single healthy weight for a Beagle, because the breed comes in two height varieties. A 13-inch Beagle should weigh under 20 pounds and a 15-inch Beagle 20 to 30 pounds.

The Alaskan Malamute standard names a desirable size rather than a range. Males should be about 25 inches and 85 pounds, females about 23 inches and 75 pounds.

The English Mastiff has the widest weight range of any common breed. The AKC lists 160 to 230 pounds for males and 120 to 170 pounds for females, and the breed standard sets no upper limit at all.

A healthy adult Bichon Frise usually weighs 12 to 18 pounds. The breed standard only specifies height, 9½ to 11½ inches at the shoulder, so weight follows from how tall and how solidly built the dog is.

The Maltese standard gives weight rather than height. Adult Maltese should weigh under 7 pounds, and 4 to 6 pounds is preferred.

Adult Lhasa Apsos usually weigh 12 to 18 pounds. The breed standard asks for a dog ideally 10 to 11 inches at the shoulder and leaves weight to the dog's build.

"Cocker Spaniel" covers two breeds. In the US the name usually means the American Cocker, 20 to 30 pounds. The English Cocker is taller and heavier at 26 to 34 pounds.

The Bouvier des Flandres weighs 70 to 110 pounds as an adult. The breed standard gives height rather than weight, with an ideal of 26 inches for males and 25 inches for females.

A cat's first year equals about 15 human years and its second about 9 more, so a 2-year-old cat is roughly 24. After that, each cat year counts as about 4 human years.

A crate that is big enough for the dog can still be refused, and a crate that passes at one airline can fail at the next.

"Size up" is repeated everywhere as though it were one rule. For crates it is often the wrong one.

The two situations where collars cause the most injuries are the two where owners think least about them.
