As the cold weather seems unrelenting, I thought a note on how best to look after your dogs in this cold spell would be useful.
Battersea have a good summary of the points needed in the link below:
Beware Rock Salt on Pavements
Also, not mentioned in the Battersea notes are that if rock salt has been spread on the ground and your dog licks at his/her paws, it is poisonous so please be aware of this – it can also cause burns to the mouth and dehydration.
Keep Antifreeze away from Pets
Remember too that if you are using antifreeze this is poisonous (and especially so to cats who find its sweet taste quite appealing and just a few drops to cats can be fatal).
