Adopting an 8 year old lab

Hi,

My partner (26), and I (24), are planning on adopting a dog. We were initially thinking around the ages 3-6, Golden retriever or Labrador but have found an 8 year old black lab that needs to be adopted.

My concern is that 8 isn’t a young dog and if we adopt her I will fall in love and be heart broken when her time comes. I understand that will happen with every dog eventually but adopting an 8 year old dog speeds that up.

Would love any thoughts on this, and advice on what to do.

Thank you!
