I'm drafting assessment criteria and actions for dehydration in rats and mice. I would like your opinion on:
- Any sign of slow return of raised skin = 5% dehydration -> oral or parenteral fluid administration
- Skin tenting = 10% dehydration = parenteral fluid administration + contact Designated Veterinarian (DV)
- Pronounced skin tenting / sunken eyes / listlessness = 15% + dehydration = contact DV to consider whether to treat or to euthanasia.
Here are some references:
What I found helpful is that weight loss should also be associated with dehydration, so I would consider it in the checkpoints.
Also, I would add the amount/type for fluid replacement (I concluded to 0.1-0.2ml LR/10gr sc).
You can also consider adding more accessible water/hydrogels.
