Determining the pet's quality of life is the most important factor in deciding when it is time to consider euthanasia.

This should include things such as:

• Is your pet able to eat and drink?
• Is your pet able to urinate and defecate without
  soiling his or herself?
• Is your pet in pain (crying or vocalizing excessively)?
• Is your pet able to rest/sleep comfortably?
• Does your pet have difficulty breathing?
• Does your pet greet/recognize you?
