How SSRIs work
SSRI stands for selective serotonin reuptake inhibitor and affects naturally occurring chemical messengers (neurotransmitters), which are used to communicate between brain cells. Specifically, SSRIs block the reabsorption (reuptake) of the neurotransmitter serotonin in the brain. Sometimes, our brains do not allow serotonin to be released to it's intended destination. It just never makes it across the gaps so it goes back home. Lazy, like me. Changing the balance of serotonin seems to help brain cells send and receive chemical messages, which in turn boosts mood. SSRIs are called selective because they seem to primarily affect serotonin, not other neurotransmitters. This is why they can be so effective.
However, the medicine can only chemically alter the state of the brain whilst it is in use. This means that a setback can occur in behavior, for example, should the drug be discontinued. Also, it is common for the drug to reduce in efficacy when used in isolation as the brain has a remarkable ability to adapt to/overcome chemical intervention.
Therefore, the above suggestion that an animal behaviorist/psychologist is consulted is excellent. The medicine can allow for chemical change so that the dog is receptive to training and training will then allow for a permanent change in the mind.
I would suggest talking to your vet, at length, about how to incorporate training and medicine and possibly agree on a time limit for improvement before alternate treatment is considered. It is my understanding that meds like these are usually given on a temp basis due the aforementioned reasons + most of the issues with behavior are not due to disorder in brain functioning but lack of training etc This would make sense for your dog given the sporadic lack of stability in homing. |
