I agree that what these people have done is wrong, and I also think egglady was right to bring it to the attention of the SS. Unfortunately, though, the law is an ass.
I also happen to believe that to allow a dog (or a horse) to live its life in an obese condition is neglectful, and owners of such animals should be taken to task. Some people just shouldn't be allowed to keep animals.
1. Freedom from hunger and thirst
2. Freedom from discomfort
3. Freedom from pain, injury and disease
4. Freedom to express normal behaviour
5. Freedom from fear and distress
dannidub...this is the point I try to make here. These five freedoms are not worth the paper they are written on. If the dog in question is in airy, dry, clean accomodation; has a reasonably comfortable bed; has regular feed and water; is free from injury; can walk around and bark; is in familiar surroundings with nothing to be afraid of, these criteria have been met. Therefore, the SS can do nothing about it. They may want to speak to the owners and give them advice on diets for healthy dogs, and may even give them a warning that if they do this again they will be recommended for prosecution.
By leaving notes and/or instructions, to 'responsible' individuals, charging others with the care of the dog, the owners have further strengthened their immunity from, and weakened the case for, prosecution or, at least, seizure of the dog.
I have long said that leaving the welfare of animals to a non-governmental, public-funded, quasi-authoratative bunch of individuals, arming them with a set of rules which take months of legal work to interpret, and furnishing them with the power to incite the police to support them, does very little other than alienate the public and leave animals open to abuse.
