L-Tyrosine is s naturally occurring amino acid ( building blocks of protein), which is being used in people, and now for pets for treating anxiety, behavioural problems.
L-Tyrosine is natural amino acid that seems to decrease symptoms of anxiety while improving mood and helping people maintain a positive outlook.
L-Tyrosine can be found in food sources such as chicken, turkey, fish, soy and dairy products, peanuts, almonds, avocados, bananas, milk, cheese, yogurt, lima beans, pumpkin seeds, sesame seeds.
L-Tyrosine has been promoted as an effective treatment for people who experience General Anxiety Disorder. Users have found that taking a small dosage of this supplement every day can help them cope with their anxiety symptoms and counteract some of the negative effects of other conventional drugs. L-Tyrosine influences the synthesis of a number of neurotransmitters and hormones within the brain that control stress levels.
Tyrosine for Dogs
This is a summary of a recent paper.
Tyrosine as a Training Aid
Certain canine behaviors (eg, easy distraction, low attention span) can resemble those of children with ADHD. Catecholamine levels (which might be correlated with ADHD) and training ease were examined in 3 dog breeds (ie, German shepherd dogs, Labrador retrievers, toy poodles) given oral tyrosine, which can increase catecholamine levels in the brain. Peripheral catecholamine levels were seemingly unchanged after daily oral tyrosine administration; however, the number of successful reactions to commands and reaction times to unknown stimuli in the shepherd dogs and retrievers improved significantly, suggesting the potential importance of neuronal catecholamine for appropriate attention levels.
1.Oral tyrosine changed the responses to commands in German shepherds and Labrador retrievers but not in toy poodles. Kano M, Uchiyama H, Ohta M, Ohtani N. J Vet Behav doi:10.1016/j.jveb.2014.12.009.
Doses: L-Tyrosine use a dosage range of 100-150mg/kg bodyweight for people, but doses vary widely.
L Tyrosine is typically sold in 500mg capsules. A suggested starting dose is 10-20mg/kg divided twice daily.
My 50lb (25kg) dog would take 1-2 capsules daily.
