Sorry to hear your sad news.
Lost my beautiful Ridgeback in March very very quickly. Walking her on Sunday spotted some blood in her urine, hospitalised then the call to get there asap.
Cried like a child. Still have her brother but the loss hit me harder than I thought. Irreplaceable.
Think of the warmth love and happiness you shared.
If you need support there is a community called Rainbow Bridge (google it and its there) for help with the loss of your pet. Only pet owners can understand.
Man hugs.
