Hope Wolf Cub is feeling better today. As said above, one dose of Pepcid lowers acid production, pretty much for the whole day, which gives the tummy chance to settle. Pepto much more short term to neutralize what is there. If he can't hold down water today then I think it is vet time. They can become dehydrated very quickly. The vet may want to give a Cerenia injection to stop the vomiting, and/or do blood tests to find the cause.
Started Primal June 2012 at 148.5lbs, and 5' 1", reached goal weight in 5 months.
Lowest weight 93lbs - too thin. Now stable at around 100lbs much better weight for me at my age.
Primal, minus eggs, dairy and a myriad of other allergens.
