A friend came from Texas with her catahoula to visit her family. Due to a mix up in communications the dog cannot stay with her in the family home. So she asked us to dog sit for a few weeks. He has been here two previous times and got a long well,played with our golden,ect. She dropped him off last night,when she left he cried just a little but settled in for the night well. Ate this morning okay. But since then he has been mopey and sad,not wanting to play or interact with me. My heart aches for this little guy. Is there anything I can do to make him a little happier? He is 3 years old and had a rough start,no history for the first 4 months of his life. He's bilingual but understands more spanish then english. Any suggestions? Any and all help is greatly appreciated. Would fussing over him reinforce his sadness?
