Azotemia in pets refers to an excess of urea or creatinine (both nitrogen-containing compounds) in your pet's blood. This condition is often related to an insufficiency in the filtering of your pet's blood by his kidneys, and is most commonly characterized by a loss of appetite. Your pet may also be weak and experience unsteadiness when walking. Other symptoms may include constipation, diarrhea, or dull fur. Your pet may also be dehydrated. How do your know if your pet is dehydrated? Thirst is not a reliable indicator, because animals suffering severe dehydration might be too weak to drink. Luckily, the elasticity of an animal’s skin is a pretty good gauge of hydration or dehydration. Find some loose skin — either on the top of the head or the base (scruff) of the neck, squeeze gently between your fingers and pull the loose skin upward. Normally hydrated skin should spring back in place immediately. Severely dehydrated skin remains standing where you squeezed it; moderately dehydrated skin returns slowly. If you suspect that your pet may be suffering from azotemia, do not delay in seeking veterinary medical help. Prompt attention to this condition can reduce further harm.
