Question

The label on a bottle of pet vitamins lists dosage guidelines. What dosage would you give to each of these animals?

1. a 18 kg adult dog
2. a 6 kg cat
3. a 18 kg pregnant dog

Do Good Pet Vitamins Adult dogs: `1/2` tsp (tea spoon full) per 9kg body weight Puppies, pregnant dogs, or nursing dogs: `1/2` tsp per 4.5kg body weight Cats: `1/4` tsp per 1kg body weight

Answer 1

a. Dosage prescribed for an adult dog is `1/2` tsp per 9 kg body weight.

∴ For a 18 kg adult dog, dosage = `((1/2))/9 xx 18`

= `1/(2 xx 9) xx 18`

= `1/18 xx 18`

= 1 tsp

b. Dosage prescribed for a cat is `1/4` tsp per 1 kg body weight.

∴ For a 6 kg cat, dosage = `((1/4))/1 xx 6`

= `1/4 xx 6` tsp

= `6/4 = 3/2` tsp

= `1 1/2` tsp

c. Dosage prescribed for pregnant dogs is `1/2` tsp per 4.5 kg body weight.

∴ For a 18 kg pregnant dog, dosage = `((1/2))/4.5 xx 18`

= `1/(2 xx 4.5) xx 18`

= `1/9 xx 18`

= `18/9` tsp

= 2 tsp
