I recently purchased what I believe to be a Water dog from Petland. i was checking out the fish/reptile department of the store and saw a tank labeled for water dogs. a few rows over was a terrarium labeled for fire belly toads as well as tadpoles. when i looked into the terrarium i indeed did see fire belly toads and tadpoles but something else caught my eye. it was what appeared to be a very skinny Water dog. the terrarium was set up with half land(gravel) and half water. the water was roughly an inch deep and barely covered the tadpoles. I decided that i couldnt leave the water dog in that situation as he looked to be near death. so I got help from a staff member and we walked over to the terrarium and i told her i wished to purchase the tadpole that had the legs, as she went to get the net and bag she asked if i had ever owned tadpoles before, which i replied yes. so she bagged the water dog and took him up to the front and rung him up as a tadpole. i took the little guy home and put him into a 10 gallon with 4 inches of water and several hiding spots. i attempted to feed him a small chopped piece of earth worm which he accepted vigorously. he has been steady the last 3 days eating chopped bits of earth worm and wax worms and has gained a bit of weight. even with a filter i am doing 90% water changes every other day. The questions i have are is he actually a water dog? i am fairly certain he is since i have done extensive research on water dogs and tiger salamanders due to me currently owning two adult tiger salamanders for 5 years. i was also wondering why his gills are so short? any thoughts would be appreciated!
