Im so sorry to hear/read about that. I have a 3 year old german shepered named terra her birthday is christmas day so she just turned 3. She is my first dog and I had to bag my parents for almost 5 years to get her! Im sure im gonna miss her terribly when she needs to go. She is probably one of the best dogs ever! Shes so smart, obedient, submissive and we barly need to teach her anything, she only peed in the house 2 or 3 times when she was about 3 months old and never pooed in the house. She is also so loving and loves people, she couldnt hurt a fly.-litterally, she tried eating one once but she couldnt.

Already we are seeing hip issues occure many large dogs get this but german sheperds are prone to it. If you rest your hand on her hips when she walks, they click and snap constanly with the odd pop. I dred the day I say goodbye.
I have had many fish, hamsters and cats that have past. The hardest was probably my first pet wich was a drawf hamster I was so young like 8-10 years old. And i had him for almost 4 years. He died in my hands. I remeber missing school I was so sad.
I wish I could draw something for you but I play from mobile so I can't. I actually am going to an arts high school for art.
Wish you the best and hope he goes without any pain.
Ps I love his name and your last name!
