Not seeking medical advice per se, more a “what would you do” ;)
Middle aged dog with the squits, seems bright in herself, has also been eating grass to make herself throw up. All this is not alarmingly unusual.
What IS different is that her gums are pretty pale, it’s a bank holiday weekend (so everything is out-of-hours), and I’ve just committed to spend my month’s paycheck on fixing the car.
What are your odds on her actually being ILL-ill?
