Be advised that if you are giving dl-Methionine (Methionine) to your dog or
cat, keep the product in a safe location to avoid any possibility of an
overdose.  Also do not routinely over medicate your pet.

Methionine is used to prevent lawn burns by neutralizing the acidity of  the
animal's urine.

One source of methionine is Doctors Foster & Smith Lawn Guard Treats. The
package does not clearly state the hazards of an overdose ("Keep out of
reach of children and pets to prevent unwanted consumption"), however
Doctors Foster & Smith does publish an article on the side effects,
contraindications and warnings on their web site.

Before using methionine or if you are currently giving your pets methionine,
please be sure to read this important article:

An extract from the Foster & Smith web site:

     "Overdose/Toxicity
     May see lack of appetite, methemoglobinemia, Heinz body hemolytic
anemia, staggering, and cyanosis (blue-purple gum color). If metabolic
acidosis occurs, may see vomiting, excessive thirst, increased rate and
depth of breathing, abnormal heart rhythms, weakness, and depression, and
death. Doses of only two times the recommendation may cause overdose
especially in cats."

From my own experience:
---------------------------------------------------------------
If your pet overdoses on this medicine, seek *IMMEDIATE* veterinarian
attention.  Your dog may show no symptoms for 8 or more hours.  Once the
symptoms appear,  death can be imminent.  If your animal does overdose,
print the PetEducation article above and bring it to your veterinarian.
Methionine overdoses are not common and your vet may not be informed.
