Hi Emily,
What have you chosen to do with your labrador?
I'm in the same position as you. I have had my brown lab from when she was 5 weeks old. She is now 12,5 years old.... still full of energy, no health issues and is very adaptable to new environments. Australia would be her 4th country,( other ones were all within Europe) so she's never been on a long haul flight..
We had to leave Australia earlier than when she was allowed to enter the country under the quarantine rules so she is currently staying with friends of ours who have a young lab themselves and two small children. She is absolutely delighted. I get videos and photos all the time and it's almost like she has a new lease on life staying with them. She's so playful like I've never seen her before.. She has grown up with just two adults, no dogs and no kids so a pretty subdued existence, and although we are very active and take her for frequent and long walks, at home she pretty much just lazed around and slept or spent hours cuddled next to me. We have always worked full-time and therefore she always had a doggy-day care arrangement so she was hardly ever alone...
I feel like taking the decision to bringing her over would be purely for selfish reasons but the thought of leaving her with friends and me not being there during her retirement years and the feeling of abandoning her is heartbreaking for me..
I love her so much. Even as a puppy, I said to my ex he can have the house but I take the dog ..
