Do dogs pick up something before you do? For the past 2 days, both my dogs will not leave me alone.. The youngest one, where ever I sit, he has to sit on/near me and my oldest is always up stairs in my bed waiting for me to lie down and when I do, he lays on me right up against my bump and will lay at my feet all night and not move! My oldest also never used to come into the bathroom when I was using the loo or showering but now he does.. Just so odd for them to act like this! Even my mums began to notice it, when we go a walk they will pull her off her feet, but with me they walk right by my side and when I stop they sit right beside me! Just so odd! This was my oldest literally 10 mins ago! He wouldn't move till we gave him a treat 😂😂 lay on my chest and wouldn't move!!
