i suppose it depends on
1) Size of animal
2) if its one of those posh pedegrees (they tend to need insurance, registration fees, more visits to the vets due to compomised imune systems thru intensive rearing etc)
If you go to a local animal shelter and get a homeless medium sized mongrel you can feed it for about £7 per week (How much is a life worth anyway). Not only that because they're not puppies they are likely to be less boisterous and possibly even house trained already. Most of them have been abused by owners and just want a decent life, in return they offer years of endless love and companionship.
I found this article about feeding a dog
"Adult dogs don't need as much food as puppies. According to Ask the Veterinarian, when picking out dog food you want to pick a food that contains around 21 percent protein, 5 percent oil, 2.5 percent fiber and 8 percent. Aim to feed smaller-breed dogs (up to 11 pounds) three to five ounces of food per day. For dogs that are 11 to 22 pounds, feed four to six ounces per day. Dogs that are 22 to 55 pounds should eat 10 to 12 ounces of dog food per day. Larger breeds around 55 to 77 pounds need 16 to 18 ounces per day. And finally, for very large dogs"
If not just get a cat - LOL
