Grey Muzzle Quality of Life Calendar App is the first app to journal your pet's days on your iPhone/iPad. Simply download the GreyMuzzle application from the app store and create your pet's profile. Then everyday mark if your pet had a good day, bad day or neutral day. This way you can keep track of those bad days. You should mentally prepare yourself for when your pet has more bad days than good and speak to your veterinarian about intervention. Or you may decide as a family that if your pet has 30% bad days, that it is appropriate to say goodbye. The quality of life can be different based on the disease the pet is struggling with, the pet's personality and the families beliefs and abilities to care for their pet during this time. The Grey Muzzle app has a calendar so you can visualize the month at a glance as well as a summary page to see a pie chart of your pet's progress. It is simple to use and free!

Helpful app for monitoring aging pets

I got this to log my elderly cat’s days as we get close to having to make the difficult decision. It’s pretty basic but it’s a good way to keep a record of the animal’s quality of life. If they ever add a notes feature to the daily tracker, I’ll be back to increase my review to 5 stars.

Needs more basic features.

Love this app. But lacks a “stay Logged in” feature. Having to sign is every time is annoying… needs to be refined to be a much smoother experience… but my compliments on a first for this kind of app!!!!
Update and I’ll gladly give 5 stars !!!!

Very basic

I was hoping that this app would use the quality of life scale so you can rate appetite, activity, hygiene, etc. It does what it advertises, but not what I wanted, so I am deleting it.
