Susan's dog went to Heaven on day twenty four.

The regular veterinarian, who Susan allowed to inspect the dog only when absolutely necessary, wanted an outrageous sum to put her down. The last time Susan's dog required this vet's services it cost Susan over eight hundred dollars, half when Susan left the dog, the other half when she picked her up. They sucked the money from Susan's check in less time than it took her to write it out, then they handed it back to her.
Here, take it with you and go.
Anyway, they weren't getting her dog now.

Susan's dog went to nice Dr. Bob who took his time and helped deliver her to the afterlife gently, without pickpocketing her owners. Susan's daughter was very sad and sniffly so Susan cheered her up by saying 'pull my finger' then took her into the kitchen to bake some anisette toast.
