Early signs
of canine cognitive dysfunction syndrome: pacing, crying, barking without apparent reason, loss of appetite, repeated attempts to get into small spaces, getting stuck in small spaces, diminishing interaction with family members, lack of recognition of family members, turning away from previously «favorite» family members, loss of house - training, sudden fascination with mirrors and staring into them, appearing hypnotized, appearing «lost.»
The signs
of canine cognitive dysfunction are progressive with time, and are commonly missed early on in the manifestation of disease, or written off as age related quirky behavior.
