I have been taking my GSD there for a little while now, 3 occasions a check up, a skin irritation and her 2nd vaccinations, they are a good vet and very very friendly people! they love thier dogs and are very knowledgeable.
The only problem is that after hours, they refer you to a vet half way across town. Redbank plains to Underwood is rather large hike in an emergency.
But overall they exceeded my expectations for vet care and i will be taking my other pup there. With a low cost for everything. (cost does vary for what you have done, But overall low)

Approximate cost: $40-170
