Trying to make a dog or cat swallow a tablet is not always the easiest thing to do. Cats like tuna, dogs like beef.
Various flavors are available for other animals.
Commercial medicine may come in 100mg or 200mg tablets or capsules. A small kitten may need a dose of 15mg. We can make tuna flavored suspension containing 15mg per 1ml. It is dispensed with a medicine dropper so that the accurate dose is easily measured. Animal medicine manufacturers often stop producing medicines and dosage forms for which there is little demand.
