Well we've wandered into deaf dogs, so here's a tribute to Abby, in the middle pointing a wily Ks. squirrel
She was "free" when I got her brother Zach (on right and was a great dog). The breeder pointed to her and said "Guess we'll just put her down 'cause she's deaf" and home she came.
Sweet as can be and easily yard/house trained because she just followed her brother around. Spent most of the day pointing/backing Zach (driving him nuts). Never tried to take her out with plenty of other dog power at the time.
This "free" dog cost me about $2000 in vet bills and replacement dog boxes and buckets since she ate anything that wasn't metal. Came home from work one afternoon and she managed to eat the plastic handle on an outside faucet, turning it on full, and flooding part of the basement
One Sunday morning we were getting ready for church and I heard this strange noise from underneath the second floor deck where the dogs hung out. She'd discovered that she could strip the lattice work strip by strip, to her great enjoyment and compulsion.
Deaf dogs are usually not right in the brain and sure enough she developed Canine Cognitive Dysfunction at only 8 years old, and totally lost it.
